Note the following details of the code protection feature on Microchip devices:
Microchip products meet the specification contained in their particular Microchip Data Sheet.
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
Microchip is willing to work with the customer who is concerned about the integrit y of their code.
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violat ion of the Digital Millennium Copyright Act. If suc h a c t s
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Microchip received ISO/TS-16949:2002 certification for its worldwide
headquarters, design and wafer fabrication facilities in Chandler and
T empe, Arizona, Gresham, Oregon and Mountain View , California. The
Company’s quality system processes and procedures are for its PIC®
8-bit MCUs, KEELOQ® code hopping devices, Serial EEPROMs,

2.0 CPU ARCHITECTURE
OVERVIEW
This section is an overview of the CPU architecture of
the dsPIC30F. The core has a 24-bit instruction word.
The Program Counter (PC) is 23 bits wide with the
Least Significant bit (LSb) always clear (see
Section 3.1 “Program Address Space”). The Most
Significant bit (MSb) is ignored during normal program
execution, except for certain specialized instructions.
Thus, the PC can address up to 4M instruction words
of user pro gra m s p ac e. An instruction prefetch m e ch a-
nism helps maintain throughput. Program loop con-
structs, free from loop count management overhead,
are supported using the DO and REPEAT instructions,
both of which are interruptible at any point.
2.1 Core Overview
The work ing re giste r array c onsist s o f 16 x 16 -bit re gis-
ters, each of which can act as data, address or offset
registers. One working register (W15) operates as a
Software Stack Pointer for interrupts and calls.
The data space is 64 Kbytes (32K words) and is split
into two blocks, referred to as X and Y data memory.
Each block has its own independent Address Genera-
tion Unit (AGU). Most instructions operate solely
through the X memory, AGU, which provides the
appearance of a single unified data space. The
Multiply-Accumulate (MAC) class of dual source DSP
instructions operate through both the X and Y AGUs,
splitting the data address space into two parts (see
Section 3.2 “Data Address Space”). The X and Y
data space boundary is device specific and cannot be
altered by the user. Each data word consists of 2 bytes
and most in structions c an address da ta either as words
or bytes.
Two ways to access data in program memory are:
The upper 32 Kbytes of data space memory can
be mapped into the lower half (user space) of
program space at any 16K program word bound-
ary, defined by the 8-bit Program Space Visibility
Page (PSVPAG) register. Thus any instruction
can access program space as if it were data
space, with a limitation that the access requires
an additio nal cy cle. On ly the lowe r 16 bit s of each
instruction word can be accessed using this
method.
Linear indirect access of 32K word pages within
progra m spac e is also possibl e using any w orking
register, via table read and write instructions.
Table read and write instructions can be used to
access all 24 bits of an instruction word.
Overhead-free circular buffers (Modulo Addressing)
are supported in both X and Y address spaces. This is
primarily intended to remove the loop overhead for
DSP algorithms.
The X AGU als o support s Bit-Reve rsed Addres sing on
dest ination ef fective addresses t o greatly simplify input
or output data reordering for radix-2 FFT algorithms.
Refer to Section 4.0 “Address Generator Units” for
details on Modulo and Bit-Reversed Addressing.
The core supports Inherent (no operand), Relative,
Literal, Memory Direct, Register Direct, Register
Indirect, Register Offset and Literal Offset Addressing
modes. Instructions are associated with pre-defined
addressing modes, depending upon their functional
requirements.
For m os t i ns tru c ti o ns , the c or e i s c apa bl e of e xe c ut i ng
a data (or program data) memory read, a working reg-
ister (data) read, a data memory write and a program
(instruction) memory read per instruction cycle. As a
result, 3 operand instructions are supported, allowing
C = A+B operations to be executed in a single cycle.
A DSP engine has been included to significantly
enhance the core arithmetic capab ility and throughput.
It features a high-speed 17-bit by 17-bit multiplier, a
40-bit ALU, two 40-bit saturating accumulators and a
40-bit b idi rec tio nal b arrel shifter. Dat a in th e a cc umul a-
tor or any worki ng r egist er can be shif ted up to 15 bits
right, or 16 bits left in a single cycle. The DSP instruc-
tions ope rate sea mles sly with all other in struct ions an d
have be en desi gned for o ptimal re al-time p erforma nce.
The MAC class of instructions can concurrently fetch
two data operands from memory while multiplying two
W registers. To enable this concurrent fetching of data
operands, the data space has been split for these
instructions and linear is for all others. This has been
achiev ed in a tran sp a r en t and fle xib le mann er, by ded-
icating cert ain worki ng registe rs to e ach addre ss spac e
for the MAC class of instructions.
Note: This data sheet summarizes features of this group
of dsPIC30F devices and is not intended to be a complete
reference source. For more information on the CPU,
peripherals, register descriptions and general device
functionality, refer to the “dsPIC30F Family Reference
Manual” (DS70046). For more information on the device
instruction set and programming, refer to the “dsPIC30F/
33F Programmer’s Reference Manual” (DS70157).
dsPIC30F2011/2012/3012/3013
DS70139E-page 18 © 2006 Microchip Technology Inc.
The core does not support a multi-stage instruction
pipeline. However, a single-stage instruction prefetch
mechanism is used, which accesses and partially
decodes instructions a cycle ahead of execution, in
order to maximize available execution time. Most
instructions execute in a single cycle with certain
exceptions.
The core features a vectored exception processing
structure for traps and interrupts, with 62 independent
vectors. The exceptions consist of up to 8 traps (of
which 4 are re served ) a nd 54 interrupts . Ea ch in terru pt
is prioritized based on a us er-assigned priority between
1 and 7 (1 being the lowest priority and 7 being the
highest), in conjunction with a predetermined ‘natural
order’. Traps have fixed priorities ranging from 8 to 15.
2.2 Programmers Model
The programmer’s model is shown in Figure 2-1 and
consists of 16 x 16-bit working registers (W0 through
W15), 2 x 40-bit accumulators (ACCA and ACCB),
STATUS register (SR), Data Table Page register
(TBLPAG), Program Space Visibility Page register
(PSVPAG), DO and REPEAT registers (DOSTART,
DOEND, DCOUNT and RCOUNT) and Program
Counter (PC). The working registers can act as data,
address or offset registers. All registers are memory
mapped. W0 acts as the W register for file register
addressing.
Some of these registers have a shadow register asso-
ciated with each of them, as shown in Figure 2-1. The
shadow register is used as a temporary h olding register
and can tr ansfer its con tents to or fro m i t s hos t reg is ter
upon the occurrence of an event. None of the shadow
registers are accessible directly. The following rules
apply for transfer of registers into and out of shadows.
PUSH.S and POP.S
W0, W1, W2, W3, SR (DC, N, OV, Z and C bits
only) are transferred.
DO instruction
DOSTART, DOEND, DCOUNT shadows are
pushed on loop start and popped on loop end.
When a byte operation is performed on a working reg-
ister, only the Least Signific ant Byte (LSB) of the t arget
register is affected. However, a benefit of memory
mapped working registers is that both the Least and
Most Significant Bytes (MSB) can be manipulated
through byte-wide data memory space accesses.
2.2.1 SOFTWARE STACK POINTER/
FRAM E POIN TE R
The dsPIC® DSC devices contain a software stack.
W15 is the dedicated Software Stack Pointer (SP),
whic h is autom atically modifi ed by exce ption pro cess-
ing and subroutine calls and returns. However, W15
can be referenced by any in stru cti on in the same ma n-
ner as all ot her W register s. This sim plifies th e reading,
writing and mani pulati on of the Stack Poi nter (e .g., cre-
ating stack frames).
W15 is initialized to 0x0800 during a Reset. The user
may reprogram the SP during initialization to any
location within data space.
W14 has been dedica ted as a St a ck Frame Pointer, as
defined by the LNK and ULNK instructions. However,
W14 can be referenced by any instruction in the same
manner as all other W registers.
2.2.2 STATUS REGISTER
The dsPIC DSC core has a 16-bit STATUS register
(SR), the LSB of which is referred to as the SR Low
byte (SRL) and the MSB as the SR High byte (SRH).
See Figure 2-1 for SR layout.
SRL contains all the MCU ALU operation Status flags
(includ ing the Z bit ), as well as the CPU Inter rupt Prior-
ity Level Status bits, IPL<2:0>, and the Repeat Active
Status bit, RA. During exception processing, SRL is
concatenated with the MSB of the PC to form a com-
plete wo rd value which is then stacked.
The upper byte of the STATUS register contains the
DSP Adde r/Subtracter Status bits, the DO Loop Active
bit (DA) and the Digit Carry (DC) Status bit.
2.2.3 PROGRAM COUNT ER
The program counter is 23 bits wide; bit 0 is always
clear. Therefore, the PC can address up to 4M
instruction words.
Note: In order to protect against misaligned
stack accesses, W15<0> is always clear.

2.3 Divide Support
The dsPIC DSC devices feature a 16/16-bit signed
fraction al d iv ide ope rati on , as w ell as 32/1 6-b it a nd 1 6/
16-bit signed and unsigned integer divide operations, in
the form of single instruction iterative divides. The fol-
lowing instructions and data sizes are supported:
1. DIVF - 16/16 signed fract ion al div id e
2. DIV.sd - 32/16 signed divide
3. DIV.ud - 32/16 unsigned divide
4. DIV.s - 16/16 signed divide
5. DIV.u - 16/16 unsigned divide
The 16/16 divides are simila r to the 32/16 (same number
of iterations), but the dividend is eithe r zero-extended or
sign-extended during the first iteration.
The divide instructions must be executed within a
REPEAT loop. Any other form of execution (e.g., a
series of discrete divide instructions) will not function
correctly because the instruction flow depends on
RCOUNT. The divid e instruction does not automatica lly
set up the RCOUNT value and it must, therefore, be
explic itly and correctl y specifi ed in the REPEAT instruc-
tion, as shown in Table 2-1 (REPEAT executes the tar-
get instruction {operand value+1} times). The REPEAT
loop count must be setup for 18 iterations of the DIV/
DIVF instruction. Thus, a complete divide operation
requires 19 cycles.
TABLE 2-1: DIVIDE INSTRUCTIONS
Note: The divide flow is interruptible. However,
the user needs to save the context as
appropriate.

dsPIC30F2011/2012/3012/3013
2.4 DSP Engine
The DSP engine consists of a high-speed 17-bit x
17-bit multiplier, a barrel shifter and a 40-bit adder/
subtracter (with two target accumulators, round and
saturati on log ic ).
The DSP engine also has the capability to perform
inherent accumulator-to-accumulator operations,
which require no additional d ata. These in structions are
ADD, SUB and NEG.
The dsPIC30F is a single-cycle instruction flow archi-
tecture, therefore, concurrent operation of the DSP
engine with MCU instruction flow is not possible.
However, some MCU ALU and DSP engine resources
may be used concurrently by the same in struction (e.g.,
ED, EDAC). See Table 2-2.
The DSP engine has various options selected through
various bits in the CPU Core Configuration register
(CORCON), as listed below:
1. Fractional or integer DSP multiply (IF).
2. Signed or unsigned DSP multiply (US).
3. Conventional or convergent rounding (RND).

2.4.1 MULTIPLIER
The 17 x 17-bit multiplier is capable of signed or
unsign ed ope ration an d can m ultiplex its output u sing a
scaler to support either 1.31 fractional (Q31) or 32-bit
integer results. Unsigned operands are zero-extended
into the 17th bit of the multiplier input value. Signed
operands are sign-exten ded into the 17th bit of the mul-
tiplier input value. The output of the 17 x 17-bit multi-
plier/scaler is a 33-bit value which is sign-extended to
40 bits. Integer data is inherently represented as a
signed two’s complement value, where the MSB is
defined as a sign bit. Generally speaking, the range of
an N- bit tw o’s comple ment in teger i s -2N-1 to 2N-1 – 1.
For a 16-bit integer, the data range is -32768 (0x8000)
to 32767 (0x7FFF) including ‘0’. For a 32-bit integer,
the data range is -2,147,483,648 (0x8000 0000) to
2,147,48 3,6 45 (0x7 FFF FFFF).
When the multiplier is configured for fractional multipli-
cation, the data is represented as a two’s complement
fraction , where the M SB is define d as a sign b it and the
radix po int is im plied to lie just a fter the si gn bit (QX f or-
mat). The range of an N-bit two’s complement fraction
with this implied radix point is -1.0 to (1 – 21-N). For a
16-bit fraction, the Q15 data range is -1.0 (0x8000) to
0.999969482 (0x7FFF) including 0’ and has a preci-
sion of 3.01518x10-5. In Fractional mode, the 16x16
multipl y ope ration genera tes a 1.31 p rodu ct, whi ch ha s
a precision of 4.65661 x 10-10.
The same multiplier is used to support the MCU multi-
ply instructions, which include integer 16-bit signed,
unsigned and mixed sign multiplies.
The MUL instruction can be directed to use byte or
word-sized operands. Byte operands direct a 16-bit
result. W ord op erands dire ct a 32-bi t result to th e spec-
ified register(s) in the W array.
2.4.2 DATA ACCUMULATORS AND
ADDER/SUBTRACTER
The data accumulator consists of a 40-bit adder/
subtracter with automatic sign extension logic. It can
select one of two accumulators (A or B) as its pre-
accumulation source and post-accumulation destina-
tion. For the ADD and LAC instructions, the data to be
accum ulated or l oaded ca n be optio nally sca led via th e
barrel shifter prior to accumulation.
2.4.2.1 Adder/Subtracter, Overflow and
Saturation
The adder/subtracter is a 40-bit adder with an optional
zero input into one side and either true or complement
data into the other input. In the case of addition, the
carry/borrow input is active high and the other input is
true data (not complemented), whereas in the case of
subtrac tion, the carry/borrow input is active low and the
other input is complemented. The adder/subtracter
generates overflow Status bits SA/SB and OA/OB,
which are la tched and reflected in the ST ATUS register:
Overflow from bit 39: this is a catastrophic
overflow in which the sign of the accumulator is
destroyed.
Overflow into guard bits 32 through 39: this is a
recoverable overflow. This bit is set whenever all
the guard bits are not identical to each other.
The adder has an additional saturation block which
controls accumulat or data satu ration if selected . It uses
the result of the adder, the overflow Status bits
described above, and the SATA/B (CORCON<7:6>)
and ACCSAT (CORCON<4>) mode control bits to
determine when and to what value to saturate.
Six STATUS register bits have been provided to
support saturation and overflow. They are:
1. OA:
ACCA overflowed into guard bits
2. OB:
ACCB overflowed into guard bits
3. SA:
ACCA saturated (bit 31 overflo w and saturatio n)
or
ACCA overflowed into guard bits and saturated
(bit 39 over flow and saturation)
4. SB:
ACCB saturated (bit 31 overflo w and saturatio n)
or
ACCB overflowed into guard bits and saturated
(bit 39 over flow and saturation)
5. OAB:
Logical OR of OA and OB
6. SAB:
Logical OR of SA and SB
The OA and OB bits are modified each time data
passes through the adder/subtracter. When set, they
indicate that the most recent operation has overflowed
into the accumulator guard bits (bits 32 through 39).
The OA and OB bits can also optionally generate an
arithmetic warning trap when set and the correspond-
ing overflow trap flag enable bit (OVATE, OVBTE) in
the INTCON1 register (refer to Section 8.0 “Inter-
rupts”) is set. This allows the user to take immediate
action, for example, to correct system gain.
dsPIC30F2011/2012/3012/3013
DS70139E-page 24 © 2006 Microchip Technology Inc.
The SA and SB bits are modified each time data
passes through the adder/subtracter but can only be
cleared by the user. When set, they indicate that the
accumula tor has overfl owed it s m aximum range (b it 31
for 32-bit saturation or bit 39 for 40-bit saturation) and
will be saturated if saturation is enabled. When satura-
tion is not enabled, SA and SB default to bit 39 overflow
and thus indicate that a catastrophic overflow has
occu rred. If the COV TE bit in the INTCO N1 reg ister is
set, SA and SB bits generate an arithmetic warning trap
when saturation is disabled.
The overflow and saturation Status bits can optionally
be viewed in the STATUS register (SR) as the logical
OR of OA an d OB (in bit OAB) and the logical OR of SA
and SB (in bit SAB). Th is allows programm ers to check
one bit in the STATUS register to determine if either
accumulator has overflowed, or one bit to determine if
either a ccum ulator has satu rated. T his w ould be usefu l
for complex number arithmetic which typically uses
both the accu mulators.
The device supports three saturation and overflow
modes:
1. Bit 39 Overflow and Saturation:
When bit 39 overflow and saturation occurs, the
saturation logic load s the maximally positive 9.31
(0x7FFFFFFFFF) or maximally negative 9.31
value (0x8000000000) into the target accumula-
tor. The SA or SB bit is set and remains set until
cleared by the user. This is referred to as ‘super
saturation’ and provides protection against erro-
neous data or unexpected algorithm problems
(e.g., gain calculations).
2. Bit 31 Overflow and Saturation:
When bit 31 overflow and saturation occurs, the
saturation logic then loads the maximally posi-
tive 1.31 value (0x007FFFFFFF) or maximally
negative 1.31 value (0x0080000000) into the
target accumulator. The SA or SB bit is set and
remains set until cleared by the user. When this
Saturation mode is in effect, the guard bits are
not used, so the OA, OB or OAB bits are never
set.
3. Bit 39 Catastrophic Overflow:
The bit 39 overflow Status bit from the adder is
used to set the SA or SB bit which remains set
until cleared by the user. No saturation operation
is performed and the accumulator is allowed to
overflow (destroying its sign). If the COVTE bit in
the INTCON1 register is set, a catastrophic
ove rflow can initiate a trap exception.
2.4.2.2 Accumulator ‘Write-Back’
The MAC class of instructions (with the exception of
MPY, MPY.N, ED and EDAC) can optionally write a
rounded version of the high word (bits 31 through 16)
of the acc umulator that is not t argeted by the instruction
into dat a spac e memory. The wri te is performe d across
the X bus into combined X and Y address space. The
following addressing modes are supported:
1. W13, Registe r Dire ct:
The rounded contents of the non-target
accumulator are written into W13 as a 1.15
fraction.
2. [W13]+=2, R egister Indirect with Post-Increment:
The round ed contents of the non- target accumu-
lator are written into the address pointed to by
W13 as a 1.15 fraction. W13 is then
incremented by 2 (fo r a wo rd wr ite).
2.4.2.3 Round Logic
The round logic is a combinational block which per-
forms a conventional (biased) or convergent (unbi-
ased) round function during an accumulator write
(store). The Round mode is determined by the state of
the RND bit in the CORCON register . It generates a 16-
bit, 1.15 data value, which is passed to the data space
write satura tion logic . If rounding is not indica ted by the
instruction, a truncated 1.15 data value is stored and
the least significant word (lsw) is simply discarded.
Conventional rounding takes bit 15 of the accumulator,
zero-extends it and ad ds it to the AC CxH word (bi t s 16
through 31 of the accumulator). If the ACCxL word
(bits 0 through 15 of the accumulator) is between
0x8000 and 0xFFFF (0x8000 included), ACCxH is
incremented. If ACCxL is between 0x0000 and 0x7FFF,
ACCxH is left un ch anged. A conseque nc e of thi s alg o-
rithm is that over a succession of random rounding
operations, the value tends to be biased slightly
positive.
Convergent (or unbiased) rounding operates in the
same manner as conventional rounding, except when
ACCxL equals 0x8000. If this is the case, the LSb
(bit 16 of the accumulator) of ACCxH is examined. If it
is ‘1’, ACCxH is incremented. If it is ‘0’, ACCxH is not
modif ied . Assu min g th at bit 16 is effec tive ly ra ndom in
nature, th is s c hem e w i ll re mo ve any rou ndi ng b ias th at
may accumulate .
The SAC and SAC.R instructions store either a trun-
cated (SAC) or rounded (SAC.R) version of the cont ents
of th e ta rget ac cumu lator t o d ata memo ry vi a th e X bu s
(subject to data saturation, see Section 2.4.2.4 “Data
Space Write Saturation”). Note that for the MAC cl as s
of instructions, the accumulator write-back operation
functions in the same manner, addressing combined
MCU (X and Y) data space though the X bus. For this
class of instructions, the data is always subject to
rounding.

dsPIC30F2011/2012/3012/3013
2.4.2.4 Data Space Write Saturation
In addition to adder/subtracter saturation, writes to data
space may also be saturated but without affecting the
contents of the source accumulator. The data space
write saturation logic block accepts a 16-bit, 1.15 frac-
tional value from the round logic block as its input,
together with overflow status from the original source
(accumulator) and the 16-bit round adder. These are
combined and used to select the appropriate 1.15
fractional value as output to write to data space
memory.
If the SATDW bit in the CORCON register is set, data
(after roundi ng or trun ca tio n) is tes te d for ove rflo w and
adjusted accordingly. For input data greater than
0x007FF F, dat a written to me mory is forced to the max-
imum posit ive 1. 15 val ue, 0x7FFF. F or inp ut da ta less
than 0x FF8000, dat a wri tten to memo ry is f orced to the
maximum negative 1.15 value, 0x8000. The MSb of the
source (bit 39) is used to determine the sign of the
operand bei ng tes ted.
If the SATDW bit in the CORCON regis ter is not set , the
input data is always passed through unmodified under
all conditions.
2.4.3 BARREL SHIFTER
The barrel shifter is capable of performing up to 16-bit
arithmetic or logic right shifts, or up to 16-bit left shifts
in a single cycle. The source can be either of the two
DSP accumulators, or the X bus (to support multi-bit
shifts of register or memory data).
The sh ifter requires a s ign ed bi nary v al ue to de term in e
both the m agnitude (number of bits) and direction of the
shift op eration. A positive value shifts the o perand right.
A negative value shifts the operand left. A value of0
does not modify the operand.
The barrel shifter is 40 bits wide, thereby obtaining a
40-bit res ult for DSP shift ope rations an d a 16-bit resu lt
for MCU shift operations. Data from the X bus is pre-
sented to the barrel shifter between bit positions 16 to
31 for right shift s, and bit positi ons 0 to 16 for l eft shifts .

User program space access is restricted to the lower
4M instruction word address range (0x000000 to
0x7FFFFE) for al l acces se s other than TBLRD/TBLWT,
which uses TBLPAG<7> to determine user or configu-

Device ID, the User ID and the Configuration bits.
Otherwise, bit 23 is always clear.

3.1.1 DATA ACCESS FROM PROGRAM
MEMORY USING TABLE
INSTRUCTIONS
This arc hit ec ture f etc hes 24 -bi t w ide pro gram memo ry.
Consequently, instructions are always aligned.
However, as the architecture is modified Harvard, data
can also be present in program space.
There are two methods by which program space can
be accessed: via special table instructions, or through
the rema ppi ng of a 16K w ord prog ram space page into
the u pp e r half o f da ta space (s ee Section 3.1.2 “Data
Access from Program Memory Using Program
Space Visibility”). The TBLRDL and TBLWTL instruc-
tions offer a direct method of reading or writing the lsw
of any address within program space, without going
through da ta spac e. The TBLRDH and TBLWTH instru c-
tions are th e only metho d whereby the upp er 8 bits of a
program space word can be accessed as data.
The PC is incremented by two for each successive
24-bit program word. This allows program memory
addresses to directly map to data space addresses.
Program memory can thus be regarded as two 16-bit
word wide address sp ac es, res id ing side by si de, eac h
with the same address range. TBLRDL and TBLWTL
access th e spac e whic h co n tai ns the ls w, and TBLRDH
and TBLWTH access the space which contains the
MSB.
Figure 3-3 shows h ow th e EA is create d fo r t a ble oper-
ations and data space accesses (PSV = 1). Here,
P<23:0> refers to a program space word, whereas
D<15:0> refers to a data space word.

3.1.2 DATA ACCESS FROM PROGRAM
MEMORY USING PROGRAM
SPACE VISIBILITY
The upper 32 Kbytes of data space may optionally be
mapped into any 16K word program space page. This
provides transparent access of stored constant data
from X data space without the need to use special
instruc tio ns (i.e ., TBLRDL/H, TBLWTL/H ins tru cti ons).
Program space access through the data space occurs
if the MSb of the data space EA is set and program
space visibility is enabled by setting the PSV bit in the
Core Control register (CORCON). The functions of
CORCON are discussed in Section 2.4 “DSP
Engine”.
Data accesses to this area add an additional cycle to
the instruction being executed, since two program
memory fetch es are requ ire d.
Note that the upper half of addressable data space is
always part of the X data space. Therefore, when a
DSP ope ration uses p rogram sp ace mapp ing to acces s
this m em ory regi on , Y d ata sp ac e s ho uld typical ly co n-
tain state (variable) data for DSP operations, whereas
X data space should typically contain coefficient
(constant) da ta.
Although each dat a sp ace address, 0x8000 and higher ,
maps directly into a corresponding program memory
address (see Figure 3-6), only the lower 16 bits of the
24-bit program word are used to contain the data. The
upper 8 bits shoul d be progra mmed to forc e an illeg al
instruction to maintain machine robustness. Refer to
the “dsPIC30F/33F Programmer s Reference Manual”
(DS70157) for details on instruction encoding.
Note that by incrementing the PC by 2 for each
program memory word, the LS 15 bits of data space
addresses directly map to the LS 15 bits in the corre-
sponding program space addresses. The remaining
bits are provided by the Program Space Visibility Page
register, PSVPAG<7:0>, as shown in Figure 3-6.
For instructions that use PSV which are executed
outside a REPEAT loop:
The following instructions require one instruction
cycle in addition to the specified execution time:
-MAC class of instructions with data operand
prefetch
-MOV instr ucti ons
-MOV.D instructions
All ot her instructions require two ins truction cycles
in addition to the specified execution time of the
instruction.
For instructions that use PSV which are executed
inside a REPEAT loop:
The following instances require two instruction
cycl es in addition to th e specified execution time
of the instruction:
- Execution in the first iteration
- Execution in the last iteration
- Execution prior to exiting the loop due to an
interrupt
- Execution upon re-entering the loop after an
interr upt is servi ced
Any other iteration of the REPEAT loop allow the
instruc tion accessing da t a, using PSV, to exec ute
in a single cycle.

3.2 Data Address Space
The core has two data spaces. The data spaces can be
considered either separate (for some DSP instruc-
tions), o r as o ne u nified linear a ddre ss ran ge (fo r MC U
instruc tions). The dat a spaces are acces s ed usi ng two
Address Generation Units (AGUs) and separate data
paths.
3.2.1 DATA SPACE MEMORY MAP
The data space memory is split into two blocks, X and
Y data space. A key ele me nt of th is archi tec tur e is th at
Y space is a subset of X space, and is fully contained
within X space. In order to provide an apparent Linear
Addressing space, X and Y spaces have contiguous
addresses.
When executing any instruction other than one of the
MAC class of instructions, the X bloc k consists of the 64-
Kbyte data address space (including all Y addresses).
When executing one of the MAC class of instructions,
the X block consists of the 64-Kbyte data address
space, excluding the Y address block (for data reads
only). In other words, all other instructions regard the
entire data memory as one composite address space.
The MAC class instructions extract the Y address space
from data space and address it using EAs sourced from
W10 and W11. The remaining X data space is
address ed using W8 an d W9. Both address spaces a re
concurrently accessed only with the MAC class
instructions.
The data space memory map for the dsPIC30F2011
and dsPIC30F2012 is shown in Figure 3-7. The data
space memory map for the dsPIC30F3012 and
dsPIC30F3013 is shown in Figure 3-8.

3.2.2 DATA SPACES
The X data space is used by all instructions and sup-
ports all addressing modes. There are separate read
and write data buses. The X read data bus is the return
data path for all instructions that view data space as
combined X and Y address space. It is also the X
address space data path for the dual operand read
instructions (MAC class). The X write data bus is the
only write path to data space for all instructions.
The X dat a sp ace also su pports Modulo Address ing for
all instructions, subject to Addressing mode restric-
tions. Bit-Reversed Addressing is only supported for
writes to X data space.
The Y data space is used in concert with the X data
space by the MAC class of instructions (CLR, ED,
EDAC, MAC, MOVSAC, MPY, MPY.N and MSC) to
provide two concurrent data read paths. No writes
occur ac ros s t he Y bu s. T his cl as s of instructio ns ded i-
cates two W regi ster pointers, W10 and W11, to alway s
address Y data space, independent of X data space,
whereas W8 and W9 always address X data space.
Note that during accumulator write back, the data
address space is consi dere d a c om bin ati on of X and Y
data spaces, so the write occurs across the X bus.
Consequently, the write can be to any address in the
entire data space.
The Y data space can only be used for the data
prefetch operation associated with the MAC class of
instructions. It also supports Modulo Addressing for
automat ed c irc ul ar bu f fe r s. Of c ours e, all othe r ins tru c-
tions ca n access the Y dat a address sp ace thro ugh the
X data path as part of the composite linear space.
The boundary between the X and Y data spaces is
defined as shown in Figure 3-8 and is not user pro-
gramma ble. Shoul d an EA poin t to d ata out side it s own
assigned address space, or to a location outside phys-
ical memory, an all zero word/byte is returned. For
example, although Y address space is visible by all
non-MAC instructions using any addressing mode, an
attempt by a MAC instruction to fetch data from that
space using W8 or W9 (X space pointers) returns
0x0000.
TABLE 3-2: EFFECT OF INVALID
MEMORY ACCESSES
All Effective Addresses are 16 bits wide and point to
bytes within the data space. Therefore, the data space
address range is 64 Kbytes or 32K words.
3.2.3 DATA SPACE WIDTH
The core data width is 16 bits. All internal registers are
organ ized as 16-bit wide words. Data space mem ory is
organized in byte addressable, 16-bit wide blocks.
3.2.4 DATA ALIGNMENT
To help maintain backward compatibility with PIC®
MCU devices and improve data space memory usage
efficiency, the dsPIC30F instruction set supports both
word and byte operation s. Data is al igned in dat a mem-
ory and registers as words, but all data space EAs
resolve to bytes. Data byte reads read the complete
word th at cont ains the by te, us ing the LSb of any EA to
determine which byte to select. The selected byte is
placed onto the LSB of the X data path (no byte
acces ses are possible fro m the Y data pa th as the MAC
class of instruction can only fetch words). That is, data
memory and registers are organized as two parallel
byte wide entities with shared (word) address decode
but separate write lines. Data byte writes only write to
the corresponding side of the array or register which
matches the byte address.
As a consequence of this byte accessibility , all Ef fective
Address c alculati ons (includin g those gene rated by the
DSP operations which are restricted to word-sized
data) a re internally scale d to step through word-aligned
memory. For example, the core would recognize that
Post-Modified Register Indirect Addressing mode
[Ws++] results in a value of Ws + 1 for byte operations
and Ws + 2 for word operations.
All word accesses must be al igned to an even a ddress.
Misaligned word data fetches are not supported so
care must be taken when mixing byte and word opera-
tions, or translating from 8-bit MCU code. Shoul d a mis-
aligned read or write be attempted, an address error
trap is generated. If the error occurred on a read, the
instruction underway is completed, whereas if it
occurred on a write, the instruction is executed, but the
write does not occur. In either case, a trap is then exe-
cuted, allowing the system and/or user to examine the
machine state prior to execution of the address fault.

All byte loads into any W register are loaded into the
LSB. The MSB is not modified.
A Sign-Extend (SE) instruction is provided to allow
users to translate 8-bit signed data to 16-bit signed
values. Alternatively, for 16-bit unsigned data, users
can clear the MSB of any W register by executing a
Zero-Extend (ZE) instruction on the appropriate
address.
Although m os t i ns truc tio ns are capable of op era t ing o n
word or byte data sizes, it should be noted that some
instructions, including the DSP instructions, operate
only on words .
3.2.5 NEAR DATA SPACE
An 8-Kbyte ‘near’ data space is reserved in X address
memory space between 0x0000 and 0x1FFF, which is
directly add res sab le via a 13-bit absolut e address field
within all memory direct instructions. The remaining X
address space and all of the Y address space is
address able indirec tly. Additional ly, the whole of X da ta
space is addressable using MOV instructions, which
support memory direct addressing with a 16-bit
address field.
3.2.6 SOFTWARE STACK
The dsPI C DSC de vices cont ain a s oftware st ack. W1 5
is used as the Stack Pointer.
The Stack Pointer always points to the first available
free word and grows from lower addresses towards
higher addresses. It pre-decrements for stack pops
and post-increments for stack pushes, as shown in
Figure 3-11. Note that for a PC push during any CALL
instruc tio n, the M SB o f t he PC i s ze ro-ex te nde d b efo re
the push, ensuring that the MSB is always clear.
There is a Stack Pointer Limit register (SPLIM) associ-
ated with the Stack Pointer. SPLIM is uninitialized at
Reset. As is t he case f or t h e Stack Point er, SPL IM < 0>
is forced to ‘0’ because all stack operations must be
word aligned. Whenever an Effective Address (EA) is
generated using W15 as a source or destination
pointer, the address thus generated is compared with
the valu e i n SPL IM. If the cont ents of the Stack Po int er
(W15) and the SPLIM register are equal, and a push
operation is performed, a stack error trap does not
occur. The stack error trap occurs on a subsequent
push operation. Thus, for example, if it is desirable to
cause a stack error trap when the stack grows beyond
address 0x2000 in RAM, initialize the SPLIM with the
value, 0x1FFE.
Similarl y, a S t ack Po inter u nderf low ( stack error) tra p is
generated when the Stack Pointer address is found to
be less than 0x0800, thus preventing the stack from
interfering with the Special Function Register (SFR)
space.
A write to the SPLIM register should no t be immediately
follow ed by an ind irec t read ope rati on usi ng W15.

4.0 ADDRESS GENERATOR UNITS
The dsPIC DSC core contains two independent
address generator un its: the X AGU and Y AGU. The Y
AGU supports word-sized data reads for the DSP MAC
class of instructions only. The dsPIC DSC AGUs sup-
port three types of data addressing:
Linear Addressing
Modulo (Circular) Addressing
Bit-Revers ed Addre ss in g
Linear and Modulo Data Addressing modes can be
applied to data space or program space. Bit-Reversed
Addressi ng is on ly appli cable to data s pace a ddresses .
4.1 Instr uction Addressing Modes
The addressing modes in Table 4-1 form the basis of
the addressing modes optimized to support the specific
features of individual instructions. The addressing
modes provided in the MAC class of instructions are
somewhat different from those in the other instruction
types.
4.1.1 FILE REGISTER INSTRUCTIONS
Most fil e re gis ter i ns truc tio ns use a 13-bit ad dres s f iel d
(f) to directly address data present in the first 8192
bytes of data memory (near data space). Most file
register instructions employ a working register, W0,
whic h is den oted as WREG in these i nstruc tions. The
destination is typically either the same file register or
WREG (with the exception of the MUL instruction),
which w rites the re sult t o a re gister or regi ster p air. The
MOV instruction allows additional flexibility and can
access the entire data space during file register
operation.
4.1.2 MCU INSTRUCTIONS
The three-operand MCU instructions are of the form:
Operand 3 = Operand 1 <function> Operand 2
where O pe rand 1 is alw a ys a work in g reg ister (i.e., the
addressing mode can only be register direct), which is
referred to as Wb. Operand 2 can be a W register,
fetched from data memory or a 5-bit literal. The result
location can be either a W register or an address
location. The following addressing modes are
supported by MCU instructions:
Register Direct
Register Indirect
Register Indirect Post-modified
Register Indirect Pre-modified
5-bit or 10-bit Literal
TABLE 4-1: FUNDAMENTAL ADDRESSING MODES SUPPORTED
Note: This data sheet summarizes features of this group
of dsPIC30F devices and is not intended to be a complete
reference source. For more information on the CPU,
peripherals, register descriptions and general device
functionality, refer to the “dsPIC30F Family Reference
Manual” (DS70046). For more information on the device
instruction set and programming, refer to the “dsPIC30F/
33F Programmer’s Reference Manual“ (DS70157).
Note: Not all instructions sup port all the address-
ing modes given above. Individual
instructions may support different subsets
of these addressing modes.
Addressing Mode Description
File Register Direct The address of the File register is specified explicitly.
Register Direct The contents of a register are accessed directly.
Register Indirect The contents of Wn forms the EA.
Register Indirect Post-modified The contents of Wn forms the EA. Wn is post-modified (incremented or
decremented) by a constant value.
Register Indirect Pre-modified Wn is pre-modified (incremented or decremented) by a signed constant value
to form the EA.
Register Indirect with Register Offset The sum of Wn and Wb forms the EA.
Register Indirect with Literal Offset The sum of Wn and a literal forms the EA.

DS70139E-page 42 © 2006 Microchip Technology Inc.
4.1.3 MOVE AND ACCUMULATOR
INSTRUCTIONS
Move instructions and the DSP accumulator class of
instructions provide a greater degree of addressing
flexibility than other instructions. In addition to the
addressing modes supported by most MCU instruc-
tions, move and accumulator instructions also support
Register Indirect with Register Offset Addressing
mode, also referred to as Register Indexed mode.
In summary, the following addressing modes are
supported by move and accumulator instructions:
Register Direc t
Register Indi rec t
Register Indi rec t Post-mod ifi ed
Register Indi rec t Pre- mo dif ied
Register Indirect with Register Offset (Indexed)
Register Indirect with Literal Offset
8-bit Literal
16-bit Literal
4.1.4 MAC INSTRUCTIONS
The dual s ource op erand DSP ins tructio ns (CLR, ED,
EDAC, MAC, MPY, MPY.N, MOVSAC and MSC), als o
referred to a s MAC instruction s, utilize a si mplified se t of
addressing modes to allow the user to effectively
manipulate the data pointers through register indirect
tables.
The two source operand prefetch registers must belong
to the set {W8, W9, W10, W11}. For data reads, W8
and W9 are always directed to the X RAGU. W10 and
W11 are always directed to the Y AGU. The effective
addresses generated (before and after modification)
must, therefore, be valid addresses within X dat a space
for W8 and W9 and Y data space for W10 and W11.
In summary, the following addressing modes are
supported by the MAC class of instructions:
Register Indirect
Register Indirect Post-modified by 2
Register Indirect Post-modified by 4
Register Indirect Post-modified by 6
Register Indirect with Register Offset (Indexed)
4.1.5 OTHER INSTRUCTIONS
Besides the various addressing mo des outlin ed above,
some i nstructio ns use li teral con sta nts of various sizes.
For example, BRA (branch) instructions use 16-bit
signed l iterals to spe cify the branch de stination dire ctly ,
whereas the DISI instruction uses a 14-bit unsigned
literal field. In some instructions, such as ADD Acc, the
source of an operand or result is implied by the opc ode
it self. Cert ain opera tions, such as NOP, do not have any
operands.
4.2 Modulo Addressing
Modulo Addressing is a method of providing an auto-
mated means to support circular data buffers using
hardwa re. The obj ective is to remo ve the ne ed for so ft-
ware to perform data address boundary checks when
executing tightly looped code, as is typical in many
DSP algorithms.
Modulo Addressing can operate in either data or pro-
gram space (since the data pointer mechanism is
essentially the same for both). One circular buffer can
be support ed in e ach o f the X ( which also provide s th e
pointers int o p rogra m space) and Y d ata spaces. Mod-
ulo Addressi ng can operate on any W regist er pointer.
However, it is not advisable to use W14 or W15 for Mod-
ulo Addressing since these two registers are used as
the Stack Frame Pointer and Stack Pointer, respec-
tively.
In general, any particular circular buffer can only be
configu red to o perate in one direc tion, as t here are cer-
tain restrictions on the buffer Start address (for incre-
menting buffers), or end address (for decrementing
buffers) based upon the direction of the buffer.
The only exception to the usage restrictions is for buff-
ers th at have a pow er-of-2 len gth. As thes e buf fers sat-
isfy the S tart and end address cri teria, they ca n operate
in a Bidirectional mode (i.e., address boundary checks
are performed on both the lower and upper address
boundaries).
Note: For the MOV instructions, the addressing
mode specified in the instruction can differ
for the source and destination EA.
However, the 4-bit Wb (register offset)
field is shared between both source and
destination (but typically only used by
one).
Note: Not all instructions su pport all the address-
ing modes given above. Individual
instructions may support different subsets
of these addressing modes.
Note: Register Indirect with Register Offset
addressing is only available for W9 (in X
spa ce) and W11 (in Y space).

dsPIC30F2011/2012/3012/3013
4.2.1 START AND END ADDRESS
The Modulo Addressing s cheme requires that a start-
ing and an ending address be specified and loaded
into the 16-bit Modulo Buffer Address registers:
XMODSRT, XMODEND, YMODSRT and YMODEND
(see Table 3-3).
The leng th of a ci rcular buffer is not di rectly s pecified. It
is determined by the difference between the corre-
spondi ng S t art and end a ddresses . The maxim um pos-
sible length of the circular buffer is 32K words
(64 Kbytes).
4.2.2 W ADDRESS REGISTER
SELECTION
The Mod ulo an d Bi t-Rev ers ed Add ress in g Co ntro l re g-
ister, MODCON<15:0>, contains enable flags as well
as a W register fi eld to s pecify the W address registers.
The XWM and YWM fields se lect whic h registe rs oper-
ate with Modulo Addressing. If XWM = 15, X RAGU
and X WAGU Modulo Ad dressing is disab led. Simi larly,
if YWM = 15, Y AGU Modulo Addressing is disabled.
The X Address Space Pointer W register (XWM), to
which Modulo Addressing is to be applied, is stored in
MODCON <3:0> (see Table 3-3). Modul o Addre ssing is
enabled for X data sp ace when XWM is set to any v alue
other than ‘15 and the XMODEN bit is set at
MODCON<15>.
The Y Address Space Pointer W register (YWM), to
which Modulo Addressing is to be applied, is stored in
MODCON<7:4>. Modulo Addressing is enabled for Y
data space when YWM is set to any value other than
15’ and the YMODEN bit is set at MODCON<14>.

4.2.3 MODULO ADDRESSING
APPLICABILITY
Modulo Addressing can be applied to the Effective
Address (EA) calculation associated with any W regis-
ter. It is important to realize that the address bound-
aries ch eck for address es less than, or greate r than the
upper (for incrementing buffers), and lower (for decre-
menting buffers) boundary addresses (not just equal
to). Address changes may, therefore, jump beyond
boundaries and still be adjusted correctly.
4.3 Bit-R eversed Addressing
Bit-Reversed Addressing is intended to simplify data
re-ordering for radix-2 FFT algorithms. It is supported
by t he X AGU for data writes only.
The m odifier, which ma y be a c onstant value or reg ister
contents, is regarded as having its bit order reve rsed. The
address source and destination are kept in normal order .
Thus, the only operand requiring reversal is the modifier .
4.3. 1 BIT-REVERSED ADDRESSING
IMPLEMENTATION
Bit-Reversed Addressing is enabled when:
1. BWM (W register selection) in the MODCON
register is any value other than ‘15’ (the stack
cannot be accessed using Bit-Reversed
Addressing) and
2. the BREN bit is set in the XBREV register and
3. the addressing mode used is Register Indirect
with Pre-Increment or Post-Increment.
If the length of a bit-reversed buffer is M = 2N bytes,
then the last ‘N’ bits of the data buffer Start address
must be zero s.
XB<14:0> is th e b it-re versed addres s mo difi er o r ‘p iv ot
point’ which is typically a constant. In the case of an
FFT computation, its value is equal to half of the FFT
dat a buffer size.
When enabled, Bit-Reversed Addressing is only exe-
cuted for register indirect with pre-increment or post-
increment addressing and word-sized data writes. It
does not functi on for an y othe r addre ss ing mod e or for
byte-sized data. Normal addresses are generated
instead. When Bit-Reversed Addressing is active, the
W address pointer is always added to the address
modifie r (XB) and the o ffset assoc iat ed w it h the Regis -
ter Indi rect Addressi ng m ode i s ign ore d. In add ition, as
wor d-s iz ed da ta is a r e qu ire m en t , th e L S b of t he E A is
ignored (and always clear).
If Bit-Reversed Addressing has already been enabled
by setting the BREN (XBREV<15>) bit, then a write to
the XBREV register should not be immediately followed
by an indirect read operation using the W register that
has been designated as the bit-reversed pointer.
Note: The m odulo correcte d Effective Address is
written back to the re giste r only when Pre-
Modify or Post-Modify Addressing mode is
used to compute the Effective Address.
When an address offset (e.g., [W7+W2] ) is
used, Modulo address correction is per-
formed, but the contents of the register
remain unc han ged.
Note: All bit-reversed EA calculations assume
word-sized data (LSb of every EA is
always clear). The XB value is scaled
accordingly to generate compatible (byte)
addresses.
Note: Modulo Addressing and Bit-Reversed
Addressing should not be enabled
together . In the event that the user attempts
to do this, Bit-Reversed Addressing
assumes priority when active for the X
WAGU, and X WAGU Modulo Addressing
is disabled. However, Modulo Addressing
continues to function in the X RAGU.

5.0 FLASH PROGRAM MEMORY
The dsPIC30F family of devices contains internal pro-
gram Fla sh memory f or executing user code. Th ere are
two methods by which the user can program this
memory:
1. Run-Time Self-Programming (RTSP)
2. In-Circuit Serial Programming™ (ICSP™)
5.1 In-Ci rcuit Serial Programming
(ICSP)
dsPIC30F devices can be serially programmed while i n
the end ap plica tion ci rcuit. Th is is s imply do ne wit h two
lines for Programming Clock and Programming Data
(which are named PGC and PGD respectively), and
three other lines for Power (VDD), Ground (VSS) and
Master Cl ear (MCLR ). This allows customers to manu-
facture boards with unprogrammed devices, and then
program the microcontroller just before shipping the
product. This also allows the most recent firmware or a
custom firmware to be programmed.
5.2 Run-Time Self-Programming
(RTSP)
RTSP is accomplished using TBLRD (table read) and
TBLWT (table wr ite) ins tru cti ons .
With RTSP, the user may erase program memory, 32
instruc tions (96 bytes) at a tim e an d c an wr it e pro gram
memory data, 32 instructions (96 bytes) at a time.
5.3 Table Instruction Operation
Summary
The TBLRDL and the TBLWTL instructions are used to
read or write to bits<15:0> of program memory.
TBLRDL and TBLWTL can access program memory in
Word or Byte mode.
The TBLRDH and TBLWTH i nstructio ns are used to read
or write to bits<23:16> of program memory. TBLRDH
and TBLWTH can access program memory in Word or
Byte mode.
A 24-bit program memory address is formed using
bits<7:0> of the TBLPAG register and the Effective
Address (EA) from a W register specified in the table
instruction, as shown in Figure 5-1.

5.4 RTSP Operation
The dsPIC30F Flash program memory is organized
into rows and panels. Each row consists of 32 instruc-
tions or 96 bytes. Each panel consists of 128 rows or
4K x 24 instructions. RTSP allows the user to erase one
row (32 instructions) at a time and to program four
instructions at one time. RTSP may be used to program
multipl e program me mory p anels, but th e Table Po inter
must be changed at each panel boundary.
Each panel of program memory contains write latches
that hold 32 instructions of programming data. Prior to
the actual programming operation, the write data must
be loaded into the panel write latches. The data to be
programmed into the panel is loaded in sequential
order into the write latches; instruction 0, in str uct i on 1,
etc. T he i ns truc tio n words loaded m us t a lway s b e fro m
a 32 address boundary.
The basi c sequence for R TSP programming is to set up
a Table Poi nter, then do a series of TBLWT instructions
to load th e wri te latc hes. Program ming is perfo rmed by
setting the special bits in the NVMCON register. 32
TBLWTL and four TBLWTH instructions are required to
load the 32 instructions. If multiple panel programming
is requ ired, th e Table Poi nter needs to be changed and
the next set of multiple write latches written.
All of the table write operations are single-word writes
(2 instruction cycles), because only the table latches
are written. A programming cycle is required for
programming each row.
The Flash Program Memory is readable, writable and
erasable during normal operation over the entire VDD
range.
5.5 Control Registers
The four SFRs used to read and write the program
Flash memory are:
•NVMCON
NVMADR
NVMADRU
NVMKEY
5.5.1 NVMCON REGISTER
The NVMCON register controls which blocks are to be
erased, which memory type is to be programmed, and
start of the programming cycle.
5.5.2 NVMADR REGISTER
The NVMADR register is used to hold the lower two
bytes of the Effective Address. The NVMADR register
captures the EA<15 :0> of the last table instru ct ion that
has been executed and selects the row to write.
5.5.3 NVMADRU REGISTER
The NVMADRU register is used to hold the upper byte
of the Effective Address. The NVMADRU register cap-
tures the EA<23:16> of the last table instruction that
has been exec uted.
5.5. 4 NVMKEY REGISTER
NVMKEY is a write-only register that is used for write
protection. To start a programming or an erase
sequence, the user must consecutively write 0x55 and
0xAA to the NVMKEY register. Refer to Section 5.6
“Programming Operations” for further details.
Note: The user can also directly write to the
NVMADR and NVMADRU registers to
specify a program memory address for
erasing or programming.

dsPIC30F2011/2012/3012/3013
5.6 Programming Operati ons
A complete programming sequence is necessary for
programming or erasing the internal Flash in RTSP
mode. A progra mming operati on is nominally 2 ms ec in
duration and the processor stalls (waits) until the oper-
ation is finished. Setting the WR bit (NVMCON<15>)
starts the operation and the WR bit is automatically
cleared when the operation is finished.
5.6.1 PROGRAMMING ALGORITHM FOR
PROGRAM FLASH
The user can erase or program one row of program
Flash memory at a time. The general process is:
1. Read one row of program Flash (32 instruction
words) and store into data RAM as a data
“image”.
2. Update the data image with the desired new
data.
3. Erase pr ogram Flash row.
a) Setup NVMCON register for multi-word,
program Flash, erase, and set WREN bit.
b) Write address of row to be erased into
NVMADRU/NVMDR.
c) Write ‘55’ to NVMKEY.
d) Write ‘AA to NVMKEY.
e) Set the WR bit. This begins erase cycle.
f) CPU stalls for the duration of the erase cycle.
g) The WR bit is cleared when erase cycle
ends.
4. Write 32 instruction words of data from data
RAM “image” into the program Flash write
latches.
5. Program 32 instruction words into program
Flash.
a) Setup NVMCON register for multi-word,
program Flash, program, and set WREN
bit.
b) Write ‘55’ to NVMKEY.
c) Write ‘AA to NVMKEY.
d) Set the WR bit. This begins program cycle.
e) CPU stalls for duration of the program cycle.
f) The WR bit is cleared by the hardware
when program cycle ends.
6. Repeat step s 1 through 5 as needed to program
desired amount of program Flash memory.
5.6.2 ERASING A ROW OF PROGRAM
MEMORY
Example 5-1 shows a co de sequenc e that can be use d
to erase a row (32 instructions) of program memory.

5.6.3 LOA DING WRITE LATCHES
Example 5-2 shows a sequence of instructions that
can be used to load the 96 bytes of write latches. 32
TBLWTL and 32 TBLWTH instructions are needed to
load the w rite lat ches selected by the Tabl e Pointer.
5.6.4 INITI ATING THE PROGRAMMING
SEQUENCE
For pr otection, the w rite in itiate sequ ence f or NVMKEY
must be used to allow any erase or program operation
to procee d. After the prog ramming com mand has bee n
executed, the user must wait for the programming time
until programming is complete. The two instructio ns fol-
lowing the start of the programming sequence should
be NOPs as shown in Example 5-3.

6.0 DATA EEPROM MEMORY
The data EEPROM memory is readable and writable
during no rmal operatio n over the enti re VDD range. The
data EEPROM memory is directly mapped in the
program memory address space.
The four SFRs used to read and write the program
Flash memory are used to access data EEPROM
memory, as well. As described in Section 5.5 “Control
Registers”, these registers are:
•NVMCON
NVMADR
NVMADRU
NVMKEY
The EEPR OM data memory allows read and writ e of
single words and 16-word blocks. When interfacing to
data memory, NVMADR, in conjunction with the
NVMADRU register, are used to address the
EEPROM location being accessed. TBLRDL and
TBLWTL instructions are used to read and write data
EEPROM. The dsPIC30F devices have up to 8 Kbytes
(4K words) of data EEPROM with an address range
from 0x7FF000 to 0x7FFFFE.
A word wri te operatio n should be prec eded by an e rase
of the corresponding memory location(s). The write typ-
ically requires 2 ms to complete, but the write time
varies with voltage and tempe r atur e.
A program or erase operation on the data EEPROM
does n ot sto p the ins truc tion fl ow. The us er is r espon -
sible for waiting for the appropriate duration of time
before initiating another data EEPROM write/erase
operation. Attempting to read the data EEPROM while
a programming or erase operation is in progress results
in unspecified data.
Control bit WR initiates write operations similar to pro-
gram Flash writ es . Th is bi t c an not be cleared, only se t,
in software. They are cleared in hardware at the com-
pletion of the write operation. The inability to clear the
WR bit in software prevents the accidental or
premature termination of a write operation.
The WREN bit, when set, allows a write operation. On
power-u p, the WREN bi t is cle ar . The WRERR bit is set
when a writ e opera tion i s inte rrupted by a MC LR Reset
or a WDT Time-out Reset during normal operation. In
these situations, following Reset, the user can check
the WRERR bit and rewrite the location. The address
register NVMADR remains unchanged.
6.1 Reading the Data EEPROM
A TBLRD instruction reads a word at the current pro-
gram word address. This example uses W0 as a
pointer to data EEPROM. The result is placed in
register W4 as shown in Example 6-1.

6.2 Erasing Data EEPROM
6.2.1 ERASI NG A BLOCK OF DATA
EEPROM
In order to erase a block of data EEPROM, the
NVMADRU and NVMAD R registers must initially point
to the block of memory to be erased. Configure
NVMCON for erasing a block of data EEPROM and
set the WR and WR EN bits in the NVMCON re gister.
Setting the WR bit initiates the erase, as shown in
Example 6-2.
EXAMPLE 6-2: DATA EEPROM BLOCK ERASE
6.2.2 ERASING A WORD OF DATA
EEPROM
The NVMADRU and NVMADR regis ters must point to
the block. Select WR a block of data Flash and set the
WR and WREN bits in the NVMCON register. Setting
the WR bit initiates the erase, as shown in Example 6-
3.

6.3 Writing to the Data EEPROM
To write an EEPROM data location, the following
sequen ce must be followed :
1. Erase data EEPROM word.
a) Select word, data EEPROM erase, and set
WREN bit in NVMCO N regis ter.
b) Write address of word to be erased into
NVMADR.
c) Enable NVM interrupt (optional).
d) Write ‘55’ to NVMK EY.
e) Write ‘AA to NVMKEY.
f) Set the WR bit. This begins erase cycle.
g) Either poll NVMIF bit or wait for NVMIF
interrupt.
h) The W R bit is cleare d whe n the era se cy cle
ends.
2. Write data word into data EEPROM write
latches.
3. Program 1 data word into data EEPROM.
a) Select word, data EEPROM program, and
set WREN bit in NVMCON register.
b) Enable N VM wri te don e inte rrupt (o ptiona l).
c) Write ‘55’ to NVMKEY.
d) Write ‘AA to NVMKEY.
e) Set the WR bit. This begins program cycle.
f) Either poll NVMIF bit or wait for NVM
interrupt.
g) The WR bit is cleared when the write cycle
ends.
The write doe s not initiate if the above sequen ce is n ot
exactly followed (write 0x55 to NVMKEY, write 0xAA to
NVMCON, then set WR bit) for each word. It is strongly
recommended that interrupts be disabled during this
code segment.
Additionally, the WREN bit in NVMCON must be set to
enable writes. This mechanism prevents accidental
writes to data EEPROM due to unexpected code exe-
cution. The WREN bit should be kept clear at all times
except when updating the EEPROM. The WREN bit is
not cleared by hardware.
After a write sequence has been initiated, clearing the
WREN bit does not affect the current write cycle. The
WR bit is inhibited from bei ng s et un le ss the WREN b it
is set. The WREN bit must be set o n a previous instruc -
tion. Both WR a nd WREN c an not be se t with th e s am e
instruction.
At the completion of the write cycle, the WR bit is
cleared in ha rdware and the No nv ola til e M emory Write
Complete Interrupt Flag bit (NVMIF) is set. The user
may either enable this interrupt or poll this bit. NVMIF
must be cleared by software.
6.3.1 WRITING A WORD OF DATA
EEPROM
Once the user has erased the word to be programme d,
then a table write instruction is used to write one write
latch, as shown in Example 6-4.
6.3. 2 WRITING A BLOCK OF DATA
EEPROM
To write a block of data EEPROM, write to all sixteen
latches first, then set the NVMCON register and
program the block.

EXAMPLE 6-5: DATA EEPROM BLOCK WRITE
6.4 Write Verify
Depending on the application, good programming
practice may dictate that the value written to the mem-
ory should be verified against the original value. This
should be used in applications where excessive writes
can stress bits near the specification limit.
6.5 Protection Against Spurious Write
There are conditions when the device may not want to
write to the data EEPROM memory. To protect against
spurious EEPROM writes, various mechanisms have
been built-in. On power-up, the WREN bit is cleared;
also, the Power-up Ti mer prevents EEPROM write.
The writ e in iti ate sequence an d the WR EN bi t tog eth er
help prevent an accidental write during brown-out,
power glitch, or software malfunction.

7.0 I/O PORTS
All of the device pins (except VDD, VSS, MCLR and
OSC1/CLKI) are shared between the peripherals and
the parallel I/O ports.
All I/O input ports feature Schmitt Trigger inputs for
improved noise immunity.
7.1 Paral le l I/O (P I O ) P o rts
When a peripheral is enabled and the peripheral is
actively driving an associated pin, the use of the pin as
a general purpose output pin is disabled. The I/O pin
can be read, but the output driver for the parallel port bit
is disabled. If a peripheral is enabled, but the peripheral
is not actively driving a pin, that pin can be driven by a
port.
All port pins have three registers directly associated
with the operation of the port pin. The Data Direction
register (TRISx ) determ ines whe ther the pin is an inp ut
or an output. If the data direction bit is a ‘1’, t hen the pin
is an input. All port pins are defined as inputs after a
Reset. Reads from the latch (LATx), read the latch.
Writes to the latch, write the latch (LATx). Reads from
the port (PORTx), read the port pins and writes to the
port pins, write the latch (LATx).
Any bit and its associated data and Control registers
that are not valid for a particular device are disabled.
That means the corresponding LATx and TRISx
registers and the port pin read as zeros.
When a pin is shared with another peripheral or func-
tion that is defined as an input only, it is nevertheless
regarded as a dedicated port because there is no
other competing source of outputs.
A parallel I/O (PIO) port that shares a pin with a periph-
eral is, in general, subservient to the peripheral. The
peripheral’s output buffer data and control signals are
provided to a pair of multiplexers. The multiplexers
select whether the peripheral or the associated port
has own ership of the outp ut dat a and co ntrol si gnals of
the I/O pad cell. Figure 7-1 shows how ports are shared
with oth er perip herals and the a ssociat ed I/O c ell (p ad)
to which they are connected.
The format of the registers for the shared ports,
(PORTB, PORTC, PORTD and PORTF) are shown in
Table 7-1 through Table 7-6.

7.2 Configuring Analog Port Pins
The use of the ADPC FG and TRIS registers control the
operation of the A/D port pins. The port pins that are
desired as analog inputs must have their correspond-
ing TRIS bit set (input). If the TRIS bit is cleared
(output), the digital output level (VOH or VOL) is
converted.
When the PORT re gi ste r is rea d, all pi ns co nfi gure d a s
analog input channels are read as cleared (a low level).
Pins configured as digital inp uts will not convert an ana-
log input. Analog levels on any pin that is defined as a
digital input (including the ANx pins) may cause the
input buffer to consume current that exceeds the
device specifications.
7.2.1 I/O PORT WRITE/READ TIMING
One instruction cycle is required between a port
direction change or port write operation and a read
operation of the same port. Typically this instruction
would be a NOP.

7.3 Input Change Noti fication Module
The input change notification module provides the
dsPIC30F devices the ability to generate interrupt
requests to the processor, in response to a change of
state on selected input pins. This module is capable of
detecting input change of states even in Sleep mode,
when the cl ocks are disabled. The re are up to 10 exter-
nal signals (CN0 through CN7, CN17 and CN18) that
may be selected (enabled) for generating an interrupt
request on a chan ge of st ate.

8.0 INTERRUPTS
The dsPIC30F sensor family has up to 21 interrupt
sources and 4 pro cessor exce ptions (trap s) which m ust
be arbitrated based on a priority scheme.
The CPU i s respons ible for rea ding the I nterrupt Vector
Table (IVT) and transferring the address contained in
the interrupt vector to the program counter. The inter-
rupt vector is transferred from the program data bus
into the program counter via a 24-bit wide multiplexer
on the input of the program counter.
The Inte rrupt Vector Table (IVT) an d Alter nate In terrupt
Vector Table (AIVT) are placed near the beginning of
program memory (0x000004). The IVT and AIVT are
shown in Figure 8-1.
The interrupt controller is responsible for pre-
processing the interrupts and processor exceptions
before they are presented to the processor core. The
peripheral interrupts and traps are enabled, prioritized
and con trolled using central ized Sp ecial Functi on Reg-
isters:
IFS0<15:0>, IFS1<15:0>, IFS2<15:0>
All interrupt request flags are maintained in these
three registers. The flags are set by their respec-
tive peripherals or external signals and they are
cleared via software.
IEC0<15:0>, IEC1<15:0>, IEC2<15:0>
All interrupt enable control bits are maintained in
these three registers. These control bits are used
to individually enable interrupts from the
peripherals or external signals.
IPC0<15:0>... IPC10<7:0>
The user assignable priority level associated with
each of these 41 interrupts is held centrally in
these eleven registers.
IPL<3:0>
The current CPU priority level is explicitly stored
in the IPL bi ts. IPL<3> i s p res en t in the C ORCO N
register, whereas IPL<2:0> are present in the
STATUS register (SR) in the processor core.
INTCON1< 15:0>, INTCON2<15 :0>
Global interrupt control functions are deriv ed from
these two registers. INTCON1 contains the con-
trol and status flags for the processor exceptions.
The INTCON2 register controls the external
interrupt request signal behavior and the use of
the alternate vector table.
All interrupt sources can be user assigned to one of 7
priori ty levels, 1 thro ugh 7, via the IPCx registers . Each
interrupt source is associated with an interrupt vector,
as shown in Table 8-1. Levels 7 and 1 represent the
highest and lowest maskable priorities, respectively.
If the NSTDIS bit (INTCON1<15>) is set, nesting of
interrupts is prev en ted . Th us, i f an interrupt is c urrentl y
being serviced, processing of a new interrupt is pre-
vented even if the new interrupt is of higher priorit y than
the one currently being serviced.
Certain interrupts have specialized control bits for fea-
tures like edge or level triggered interrupts, interrupt-
on-change, etc. Control of these features remains
within the peripheral module which generates the
interrupt.
The DISI instruction can be used to disable the
processing of interrupts of priorities 6 and lower for a
certain number of instructions, during which the DISI bit
(INTCON2<14>) remains set.
When an interrupt is serviced, the PC is loaded with the
address stor ed in the vector locati on in program mem-
ory that cor res ponds to the interru pt. There are 63 dif-
feren t vectors wi thin the IVT (refer to Table 8-1). These
vectors are contained in locations 0x000004 through
0x0000FE of program memory (refer to Table 8-1).
These locations contain 24-bit addresses, and in order
to preserve robustness, an address error trap takes
place if the PC attempts to fetch any of these words
during normal execution. This prevents execution of
random dat a a s a resul t o f accide nt ally de cre menting a
PC into vector space, accidentally mapping a data
spac e addr ess in to vec tor sp ace , or the PC roll ing over
to 0x000000 after reaching the end of implemented
program memory space. Execution of a GOTO instr uc-
tion to this vector space also generates an address
error trap.
Note: This data sheet summarizes features of this group
of dsPIC30F devices and is not intended to be a complete
reference source. For more information on the CPU,
peripherals, register descriptions and general device
functionality, refer to the “dsPIC30F Family Reference
Manual” (DS70046). For more information on the device
instruction set and programming, refer to the “dsPIC30F/
33F Programmer’s Reference Manual” (DS70157). Note: Interru pt flag bit s get set when an interru pt
conditi on occ urs, regar dless o f the s tate of
its corresponding enable bit. User soft-
ware should ensure the appropriate inter-
rupt flag bits are clear prior to enabling an
interrupt.
Note: Assigning a priority level of ‘0’ to an inter-
rupt source is equivalent to disabling that
interrupt.
Note: The IPL bits become read-only whenever
the NSTDIS bit has been set to ‘1’.

DS70139E-page 64 © 2006 Microchip Technology Inc.
8.1 Interrupt Priority
The user assignable interrupt priority (IP<2:0>) bits for
each individual interrupt source are located in the LS
3 bits of each n ibble withi n the IPCx registe r(s). Bit 3 of
each nibble is not used and is read as a ‘0’. These bits
define the priority level assigned to a particular interrupt
by the user.
Natural Order Priority is determined by the position of
an interrupt in the vector table, and only affects
interrupt operation when multiple interrupts with the
same user-assigned priority become pending at the
same time.
Table 8-1 lists the interrupt numbers and interrupt
sources for the dsPIC30F2011/2012/3012/3013
devices and their associated vector numbers.
The ability for the user to assign every interrupt to one
of seven pri ority levels means that the user can as sig n
a very high overall priority level to an interrupt with a
low natural order priority. For example, the PLVD (Low
Voltage Detect) can be given a priority of 7. The INT0
(External Interrupt 0) may be assigned to priority level
1, thus giving it a very low effective priority.
TABLE 8-1: INTERRUPT VECTOR TABLE
Note: The user selectable priority levels start at
0 as the lo west pri ority an d level 7 as the
highest priority.
Note 1: The natural order priority scheme has 0
as the highest priority and 53 as the
lowest priority.
2: The natural order priority number is the
same as the INT number.

8.2 Reset Sequence
A Reset is not a true exception because the interrupt
controll er is not involv ed in the Reset proce ss. The pro-
cessor initializes its registers in response to a Reset
which forces the PC to zero. The processor then begins
program execution at location 0x000000. A GOTO
instruction is stored in the first program memory loca-
tion immediately followed by the address target for the
GOTO instruction. The processor executes the GOTO to
the speci f ie d add res s and then begi ns op erat ion at the
specified target (start) address.
8.2.1 RESET SOURCES
In addition to external Reset and Power-on Reset
(POR), there are 6 sources of error conditions which
‘trap’ to the Reset vector.
Watchdog Time-out:
The watchdog has timed out, indicating that the
process or is no longer ex ecu tin g the corre ct flo w
of code.
Uninitialized W Register Trap:
An attempt to use an uninitialized W register as
an Address Pointer causes a Reset.
Illegal Instruction Trap:
Attempted execution of any unused opcodes
results in an illegal instruction trap. Note that a
fetch of an illegal instruction does not result in an
illegal instruction trap if that instruction is flushed
prior to execution due to a flow change.
Brown-out Reset (BOR):
A momentary dip in the power supply to the
device has been detected which may result in
malfunction.
Trap Lockout:
Occurrence of multiple trap condit ions
simultaneously causes a Reset.
8.3 Traps
Traps can be considered as non-maskable interrupts
indicating a software or hardware error, which adhere
to a predefined priority as shown in Figure 8-1. They
are intended to provide the user a means to correct
errone ous o pera tio n d urin g debug and w he n o pera tin g
within the application.
Note that many of these trap conditions can only be
detected when th ey occur. Conseque ntly, the ques tion-
able instruction is allowed to complete prior to trap
exception processing. If the user chooses to recover
from the error, the result of the erroneous action that
caused the trap may have to be corrected.
There are 8 fixed priority levels for traps: Level 8
through Le ve l 15, whic h impl ies tha t the IPL3 i s alw ays
set during processing of a trap.
If the us er is n ot cur rentl y execu ting a trap, a nd he s et s
the IP L<3:0> bit s to a value of 0111’ (Level 7), t hen al l
interr upts are disabled, b ut traps c an still b e processed.
8.3.1 TRAP SOURCES
The following traps are provided with increasing prior-
ity. However, since all traps can be nested, priority has
little effect.
Math Error Trap:
The math error t r ap e xe cutes und er th e following thre e
circumstances:
1. If an attempt is made to divide by zero, the
divide operation is aborted on a cycle boundary
and the trap is taken.
2. If enabled, a math error trap is taken when an
arithmetic operation on either accumulator A or
B causes an overflow from bit 31 and the accu-
mulator guard bits are not utilized.
3. If enabled, a math error trap is taken when an
arithmetic operation on either accumulator A or
B causes a catast rophic overflow from bit 39 and
all saturation is disabled.
4. If the shift amount specified in a shift instruction
is greater than the maximum allowed shift
amount, a trap occurs.
Note: If the user does not intend to take correc-
tive action in the event of a trap error
condition, these vectors must be loaded
with the address of a default handler that
simply contains the RESET instruction. If,
on the other hand, one of the vectors
containing an invalid address is called, an
address error trap is generated.
dsPIC30F2011/2012/3012/3013
DS70139E-page 66 © 2006 Microchip Technology Inc.
Address Error Trap:
This trap is initiated when any of the following
circumstances occurs:
1. A misaligned data word access is attempted.
2. A data fetch from our unimplemented data
memory location is attempted.
3. A data access of an unimplemented program
memory location is attempted.
4. An instruction fetch from vector space is
attempted.
5. Execution of a “BRA #literal” instruction or a
GOTO #literal” ins truc ti on, w he re literal
is an u nimplem ented pr ogram me mory addr ess.
6. Executing instructions after modifying the PC to
point to unimplemented program memory
addresses. The PC may be modified by loading
a value into the stack and executing a RETURN
instruction.
Stack Error Trap:
This trap is initiated under the following conditions:
1. The Stack Pointer is loaded with a value which
is greater than the (user programmable) limit
value written into the SPLIM register (stack
overflow).
2. The Stack Pointer is loaded with a value which
is less than 0x0800 (simple stack underflow).
Oscillator Fail Trap:
This trap is initiated if the external oscillator fails and
operation becomes reliant on an internal RC backup.
8.3.2 HARD AND SOFT TRAPS
It is possible that multiple traps can become active
within the same cycle (e.g., a misaligned word stack
write to an overflowed address). In such a case, the
fixed priority shown in Figure 8-2 is implemented,
whic h may requir e the user t o check if oth er traps are
pending, in order to completely correct the Fault.
‘Soft’ traps incl ude exceptions of priority lev el 8 through
level 11, inclusive. The arithmetic error trap (level 11)
falls into this category of traps.
‘Hard’ traps include exceptions of priority level 12
through level 15, inclusive. The address error (level
12), stack error (level 13) and oscillator error (level 14)
traps fall into this category.
Each hard trap that occurs must be acknowledged
before code execution of any type can continue. If a
lower priority hard trap occurs while a higher priority
trap is pending, acknowledged, or is being processed,
a hard trap conflict occurs.
The devic e is automatic ally Reset in a hard trap conflict
condition. The TRAPR Status bit (RCON<15>) is set
when the Reset occurs, so that the condition may be
detected in software.
Note: In the MAC class of instructions, wherein
the data space is split into X and Y data
space, unimplemented X space includes
all of Y space, and unimplemented Y
space includes all of X space.

8.4 Interrupt Sequence
All inte rrupt event flags are sampled in the be ginning of
each instruction cycle by the IFSx registers. A pending
Interrupt Request (IRQ) is indicated by the flag bit
being equ al to a ‘1’ in an IFSx reg ister . The IRQ cau ses
an interrupt to occur if the corresponding bit in the Inter-
rupt Enable (IEC x) register is set. For the rema ind er of
the i nstruc tion cy cle, the priori ties of a ll pend ing in ter-
rupt requests are evaluated.
If there is a pending IRQ with a priority level greater
than the current processor priority level in the IPL bits,
the processor is interrupted.
The pr ocessor then st acks the curren t program counter
and the low byte of the processor STATUS register
(SRL), as shown in Figure 8-2. The low byte of the
ST ATUS register contains the processor priority level at
the time prior to the beginning of the interrupt cycle.
The pr ocessor the n loads t he priority level fo r this int er-
rupt into the STATUS register. This action disables all
lower priority interrupts until the completion of the
Interr u pt Service R outine.
FIGURE 8-2: INTERRUPT STACK
FRAME
The RETFIE (return from interrupt) instruction unstacks
the program counter and STATUS registers to return
the processor to its state prior to the interrupt
sequence.
8.5 Alter nate Vector Table
In program memory, the Interrupt Vector Table (IVT) is
follow ed by the Altern ate Interr upt Vector Table (AIVT),
as shown in Figure 8-1. Access to the alternate vector
table is provided by the ALTIVT bit in the INTCON2 reg-
ister. If the ALTIVT bit is set, all interru pt a nd ex cep tio n
processes use the alternate vectors instead of the
defa ul t vec to r s. T h e alt er na t e v e ctor s a re or g ani ze d in
the same manner as the de fault vectors. The AIVT sup-
ports emulation and debugging efforts by providing a
means to sw i tch betw e en an ap pli ca t io n and a su ppo rt
environment without requiring the interrupt vectors to
be reprogram m ed. Th is featu re als o ena bl es s w itchin g
between applications for evaluation of different
software algorithms at run time.
If the AIVT is not required, the program memory allo-
cated to the AIVT may be used for other purposes.
AIVT is not a protected section and may be freely
programmed by the user.

Note 1: The user can always lower the priority
level by writing a new value into SR. The
Interrupt Service Routine must clear the
interrupt flag bits in the IFSx register
before lowering the processor interrupt
priority, in order to avoid recursive
interrupts.
2: The IPL3 bit (CORCON<3>) is always
clear when interrupts are being pro-
cessed. It is set only during execution of
traps.

8.6 Fast Context Saving
A context saving option is available using shadow reg-
isters. Shadow registers are provided for the DC, N,
OV, Z and C bits in SR, and the registers W0 through
W3. The s hadows are only o ne level deep. Th e shadow
registers are accessible using the PUSH.S and POP.S
instruc tions only.
When the processor vectors to an interrupt, the
PUSH.S instruction can be used to store the current
value of the aforementioned registers into their
respective shadow registers.
If an ISR of a certain priority uses the PUSH.S and
POP.S instructions for fast context saving, then a
higher priority IS R shou ld no t inc lude the s ame instru c-
tions. Users must save the key registers in software
during a lo wer priori ty interru pt if the h igher priorit y ISR
uses fast context saving.
8.7 External Interrupt Requests
The interrupt controller supports three external inter-
rupt request signals, INT0-INT2. These inputs are edge
sensitive; they require a low-to-high or a high-to-low
transition to generate an interrupt request. The
INTCON2 re gister has thre e bits , INT0EP-INT2EP, th at
select the polarity of the edge detection circuitry.
8.8 Wake-up from Sleep and Idle
The interrupt controller may be used to wake-up the
processor from either Sleep or Idle modes, if Sleep or
Idle mode is active when the interrupt is generated.
If an enabled interrupt request of sufficient priority is
received by the interrupt controller, then the standard
interrupt request is presented to the processor. At the
same time, the processor wakes up from Sleep or Idle
and begin execution of the Interrupt Service Routine
(ISR) needed to process the int errup t reque st.

9.0 TIMER1 MODULE
This section describes the 16-bit general purpose
Timer1 module and associated operational modes.
Figure 9-1 depicts the simplified block diagram of the
16-bit Timer1 module. The following sections provide
det ailed d escriptio ns inclu ding setup a nd Control r egis-
ters, alon g with associated block diagrams for the oper-
ational modes of t he timers.
The Timer1 module is a 16-bit timer that serves as the
time counter for the real-time clock or operates as a
free-running interval timer/counter . The 16-bit timer has
the following modes:
16-bit Timer
16-bit Synchronous Counter
16-bit Asynchronous Counter
These operational characteristics are supported:
Timer gate operation
Selectable prescaler set tings
Timer operation during CPU Idle and Sleep
modes
Interrupt on 16-bit Period register match or falling
edge of external gate signal
These operating modes are determined by setting the
appropriate bit(s) in the 16-bit SFR, T1CON. Figure 9-1
present s a block diagram o f the 16-bit timer modul e.
16-bit T imer Mode: In t he 16-bi t T imer m ode, the timer
increments on every instruction cycle up to a match
value preloaded into the Period register PR1, then
resets to ‘0’ and continues to count.
When the CPU go es into t he Idle mode , the time r stop s
incrementing unless the TSIDL (T1CON<13>) bit = 0.
If TSIDL = 1, the timer m odule logic resu mes th e inc re-
menting sequence on termination of CPU Idle mode.
16-bit Synchronous Counter Mode: In the 16-bit
Synchronous Counter mode, the timer increments on
the rising edge of the applied external clock signal
which is synchronized with the internal phase clocks.
The timer counts up to a match value preloaded in PR1,
then reset s to ‘0’ and conti nue s.
When the CPU go es into t he Idle m ode, the ti mer stop s
incrementing unless the respective TSIDL bit = 0. If
TSIDL = 1, the timer module logic resumes the incre-
menting sequence upon termination of the CPU Idle
mode.
16-bit Asynchronous Counter Mode: In the 16-bit
Asynchronous Counter mode, the timer increments on
every rising edge of the applied external clock signal.
The timer counts up to a match value preloaded in PR1,
then reset s to ‘0’ and conti nue s.
When the timer is configured for the Asynchronous
mode of operation and the CPU goes into the Idle
mode, the timer stops incrementing if TSIDL = 1.

9.1 Timer Gate Operation
The 16-bi t timer can be pl aced in the Ga ted Ti me Accu-
mulation mode. This mode allows the internal TCY to
increm ent the respec tive timer when the gate input si g-
nal (T1CK pin) is asserted high. Control bit, TGATE
(T1CON<6>), must be set to enable this mode. The
timer must be enabled (TON = 1) and the timer clock
source se t to interna l (TCS = 0).
When the CPU go es into t he Idle m ode, the ti mer stop s
increm enti ng unless TSID L = 0. If TSIDL = 1, the timer
resumes the incrementing sequence upon termination
of the CPU Idle mode.
9.2 Timer Prescaler
The input clock (FOSC/4 or external clock) to the 16-bit
T imer has a pre scale optio n of 1:1, 1:8, 1:64 a nd 1:256,
selected by control bits, TCKPS<1:0> (T1CON<5:4>).
The prescaler counter is cleared when any of the
following occurs:
a write to the TMR1 register
a write to the T1CON register
device Reset, su ch as POR and BOR
However, if the timer is disabled (TON = 0), then the
timer prescaler cannot be reset since the prescaler
clock is halted.
TMR1 is not cleared when T1CON is written. It is
cleared by writin g to the TMR1 register.
9.3 Timer Operation During Sleep
Mode
The timer operates during CPU Sleep mode if:
The timer module is enabled (TON = 1), and
The timer clock source is selected as external
(TCS = 1), and
The TSYNC bit (T1CO N<2>) is asserted to a log ic
0’ which defines the exter nal clock source as
asynchronous.
When all three conditions are true, the timer continues
to count up to the Period register and be reset to
0x0000.
When a ma tch between th e timer and the Peri od regi s-
ter occurs, an interrupt can be generated if the
respective timer interrupt enable bit is asserted.
9.4 Timer Interrupt
The 16-bit timer has the ability to generate an interrupt-
on-period match. When the timer count matches the
Peri od regis ter, the T1I F bit is asse rted an d an inte rrupt
is gene rat ed , if enabled. The T1IF bit must be cleared in
software. The timer interrupt flag, T1IF, is located in the
IFS0 Control register in the interrupt controller .
When the Gated Time Accumulation mode is enabled,
an interrupt is al so ge nerated on the falling edg e o f the
gate signal (at the end of the accumulation cycle).
Enabling an interrupt is accomplished via the respec-
tive timer interrupt enable bit, T1IE. The timer interrupt
enable bit is located in the IEC0 Control register in the
interrupt controller.
9.5 Real-Time Clock
Timer1, when operating in Real-Time Clock (RTC)
mode, provides time of day and event time-stamping
capabilities. Key operation al features of the RTC are:
Operation from 32 kHz LP oscillator
8-bit presc ale r
•Low power
Real-Time Clock interrupts
These operating modes are determined by setting the
appropriate bit(s) in the T1CON Control register.

9.5.1 RTC OSCILLATOR OPERATION
When the T ON = 1, T CS = 1 and TGATE = 0, the timer
increm ents on th e ris in g e dge of the 32 kHz LP oscill a-
tor output si gnal, up to the val ue specified in the Period
register and is then reset to0’.
The TSYNC bit must be asserted to a logic ‘0
(Asynchronous mode) for correct operation.
Enabling LPOSCEN (OSCCON<1>) disables the
normal Timer and Counter modes and enables a timer
carry-out wake-up event.
When the CPU ente rs Sleep mod e, the RTC co nti nues
to opera te, provid ed the 32 kHz e xternal c rystal oscill a-
tor is active and the control bits have not been
changed. The TSIDL bit should be cleared to 0’ in
order for RTC to continue operation in Idle mode.
9.5.2 RTC INTERRUPTS
When an interrupt event oc curs, the respectiv e interrupt
flag, T1IF, is asserted and an interrupt is generated if
enabled. The T1IF bit must be cleared in software. The
respective Timer interrupt flag, T1IF, is located in the
IFS0 register in the interrupt con troller.
Enabling an interrupt is accomplished via the respec-
tive timer interrupt enable bit, T1IE. The timer interrupt
enable bit is located in the IEC0 Control register in the
interrupt con trol le r.

10.0 TIMER2/3 MODULE
This section describes the 32-bit general purpose
Timer module (Timer2/3) and associated Operational
modes. Figure 10-1 depicts the simplified block dia-
gram of the 32-bit Timer2/3 module. Figure 10-2 and
Figure 10-3 show Timer2/3 configured as two
independent 16-bit timers, Timer2 and Timer3,
respectively.
The Timer2/3 module is a 32-bit timer (which can be
configured as two 16-bit timers) with selectable
operating modes. These timers are utilized by other
periphe ral modul es, such as:
Input Capture
Output Compare/Simpl e PWM
The following sections provide a detailed description,
including setup and Control registers, along with asso-
ciated block diagrams for the operational modes of the
timers.
The 32-bit timer has the following modes:
Two independent 16-bit timers (Timer2 and
Tim er3) with all 16 -bit operating mode s (except
Asynchronous Counter mode)
Single 32-bit timer operation
Single 32-bit synchronous counter
Further, the following operational characteristics are
supported:
AD C event trigger
Timer gate operation
Selectable prescaler set tings
Timer operation during Idle and Sleep modes
Interrupt on a 32-bit peri od register match
These operating modes are determined by setting the
appropriate bit(s) in the 16-bit T2CON and T3CON
SFRs.
For 32-bit timer/counter o peration, Timer2 is the ls word
and Timer3 is the ms word of the 32-bit timer.
16-bit Timer Mode: In the 16-bit mode, Timer2 and
Timer3 can be configured as two independent 16-bit
timers. Each timer can be set up in either 16-bit Timer
mode or 16-bit Synchronous Counter mode. See
Section 9.0 “Timer1 Mo dule for details on these two
operating modes.
The only functional difference between Timer2 and
Timer3 is that Timer2 provides synchronization of the
clock prescal er output. This is usefu l for high frequenc y
external clock inputs.
32-bit T imer Mode: In t he 32-bi t T imer m ode, the timer
increments on every instruction cycle, up to a match
value preloaded into the combined 32-bit Period
register PR3/PR2, then resets to ‘0’ and continues to
count.
For synchronous 32-bit reads of the Timer2/Timer3
pair , reading the ls wo rd (TMR2 register) causes the ms
word to be rea d a nd lat che d i nto a 16-b it hol ding regis-
ter, termed TMR3HLD.
For synchronous 32-bit writes, the holding register
(TMR3HLD) must first be written to. When followed by
a write to the TMR2 re gister, the content s of TM R3HLD
is transferred and latched into the MSB of the 32-bit
timer (TMR3).
32-bit Synchronous Counter Mode: In the 32-bit
Synchronous Counter mode, the timer increments on
the rising edge of the applied external clock signal
which is synchronized with the internal phase clocks.
The timer counts up to a match value preloaded in the
combi ne d 32 -bi t per i od re gi st er, PR3/PR 2 , th en re se ts
to ‘0’ and continues.
When the timer is configured for the Synchronous
Counter mode of operation and the CPU goes into the
Idle mode, the timer stops incrementing unless the
TSIDL (T2CON<13>) bit = 0. If TSIDL = 1, the timer
module logic resumes the incrementing sequence
upon termination of the CPU Idle mode.
Note: This data sheet summarizes features of this group
of dsPIC30F devices and is not intended to be a complete
reference source. For more information on the CPU,
peripherals, register descriptions and general device
functionality, refer to the “dsPIC30F Family Reference
Manual “(DS70046).
Note: For 32-bit timer operation, T3CON control
bits are ignored. Only T2CON control bits
are used for setup and control. Timer2
clock and gate inputs are utilized for the
32-bit timer module, but an interrupt is
generated with the Timer3 interrupt flag
(T3IF) and th e interrupt is en abled with the
Timer3 interrupt enable bit (T3IE).

10.1 Timer Gate Operation
The 32-bi t timer can be pl aced in the Ga ted Ti me Accu-
mulation mode. This mode allows the internal TCY to
increm ent the respec tive timer when the gate input si g-
nal (T2CK pin) is asserted high. Control bit, TGATE
(T2CON<6>), must be set to enable this mode. When
in this mode, Timer2 is the originating clock source.
The TGATE setting is ignored for Timer3. The timer
must be e nab led (T O N = 1) and the time r cl oc k so urc e
set to internal (TCS = 0).
The falling edge of the external signal terminates the
count operation but does not reset the timer. The user
must reset the timer in order to start counting from zero.
10.2 ADC Event Trigger
When a matc h occurs betwe en the 32-bit timer (TM R3/
TMR2) and the 32-bit combined period register (PR3/
PR2), or be twee n the 16-b it ti me r TM R3 and the 16-b it
period re gister PR3 , a spe cial ADC tri gger ev ent si gnal
is generated by Timer3.
10.3 Timer Prescaler
The in put cloc k (FOSC/4 or external clock) to the timer
has a prescale option of 1:1, 1:8, 1:64, and 1:256,
selected by control bits, TCKPS<1:0> (T2CON<5:4>
and T3CON<5:4>). For the 32-bit timer operation, the
origina ting clock so urce is Timer2. Th e prescale r oper-
ation for Timer3 is not applicable in this mode. The
prescaler counter is cleared when any of the following
occurs:
a write to the TMR2/TMR3 register
a write to the T2CON/T3CON register
device Reset, su ch as POR and BOR
However, if the timer is disabled (TON = 0), then the
Timer 2 prescaler cannot be reset since the prescaler
clock is halted.
TMR2/TMR3 is not cleared when T2CON/T3CON is
written.
10.4 Timer Operation During Sleep
Mode
The timer does not operate during CPU Sleep mode
because the internal clocks are disabled.
10.5 Timer Interrupt
The 32-bit timer module can generate an interrupt-on-
period ma tch or on the fall ing edg e of the ext ernal ga te
signal. When the 32-bit timer count matches the
respective 32-bit period register, or the falling edge of
the external “gate” signal is detected, the T3IF bit
(IFS0<7>) is asserted and an interrupt is generated if
enabled . In this mode, th e T3IF int errupt fl ag is used as
the source of the interrupt. The T3IF bit must be
cleared in software.
Enabling an interrupt is accomplished via the
respective timer interrupt enable bit, T3IE (IEC0<7>).

11.0 INPUT CAPTURE MODULE
This section describes the input capture module and
associated operational modes. The features provided
by this module are useful in applications requiring fre-
quency (period) and pulse measurement.
Figure 11-1 depicts a block diagram of the input cap-
ture modu le. Input cap ture is useful fo r such mode s as:
Frequency/Period/Pulse Measurements
Additional Sources of External Interrupts
Important operational features of the input capture
module are:
Simple Capture Event mode
Timer2 and Timer3 mode selection
Interrupt on input capture event
These operating modes are determined by setting the
appropria te bits in the IC1CON and IC2C ON regis ters .
The dsP IC30F2011/2012/3 012 /30 13 de vi ces hav e tw o
capture channels.
11.1 Simple Capture Event Mode
The simple capture events in the dsPIC30F product
family are:
Capture every falling edge
Capture every rising edge
Capture every 4th rising edge
Capture every 16th rising edge
Capture every rising and falling edge
These simple Input Capture modes are configured by
setting t he appropri ate bits, IC M<2:0> (ICxC ON<2:0>).
11.1.1 CAPTURE PRESCALER
There are four input capture prescaler settings speci-
fied by bits ICM<2:0> (ICxCON<2:0>). Whenever the
capture channel is turned off, the prescaler counter is
cleared. In addition, any Reset clears the prescaler
counter.

11.1.2 CAPTURE BUFFER OPERATION
Each capture channel has an associated FIFO buffer
which is four 16-bit words deep. There are two status
flags which provide status on the FIFO buffer:
ICBNE — Input Capture Buffer Not Empty
IC OV — Input Captu re Over flow
The ICBNE is set on the first input capture event and
remains set until all capture events have been read
from the FIF O. As each word is read fro m the FIFO, th e
remaining words are advanced by one position within
the buffer.
In the event that the FIFO is full with four capture
events, and a fifth capture event occurs prior to a read
of the FIFO, an overflow condition occurs and the ICOV
bit is s et to a lo gic ‘1’. The f ifth captu re event i s lost an d
is not s tored in the FIFO . No a dditio nal ev ent s are ca p-
tured until all four events have been read from the
buffer.
If a FIFO read is performed after the last read and no
new capture event has been received, the read will
yield indeterminate results.
11.1.3 TIMER2 AND TIMER3 SELECTION
MODE
The inp ut capture mod ule cons ist s of up to 8 input cap-
ture chann els. Each channel can select between one of
two timers for the time base, Timer2 or Timer3.
Selection of the timer resource is accomplished
through SFR bit, ICTMR (ICxCON<7>). Timer3 is the
default timer resource available for the input capture
module.
11.1.4 HALL SENSOR MODE
When the input capture module is set for capture on
every ed ge, rising a nd falli ng, ICM <2:0> = 001, the fol-
lowing operations are performed by the input capture
logic:
The input capture interrupt flag is set on every
edge, rising and falling.
The interrupt on Capture mode setting bits,
ICI<1:0>, is ignored since every capture
generates an interrupt.
A capture overflow condition is not generated in
this mode.
11.2 Input Capture Operation During
Sleep and Idle Modes
An input capture event generates a device wake-up or
interrupt, if enabl ed, if the devi ce is in CPU Id le or Sleep
mode.
Independent of the timer being enabled, the input cap-
ture module wakes up from the CPU Sleep or Idle mode
when a c apture event occurs if ICM<2:0> = 111 and the
interrupt enable bit is asserted. The same wake-up can
generate an interrupt if the conditions for processing the
interrupt have been satisfied. The wake-up feature is
useful as a method of adding extra external pin inter-
rupts.
11.2.1 INPUT CAPTURE IN CPU SLEEP
MODE
CPU Sleep mode allows input capture module opera-
tion w ith reduced function ality. In the CPU Sleep mode,
the ICI<1:0> bits are not applicable and the input cap-
ture module can only function as an external interrupt
source.
The capture module must be configured for interrupt
only on rising edge (ICM<2:0> = 111) in order for the
input capture module to be used while the device is in
Sleep mode. The prescale settings of 4:1 or 16:1 are
not applicable in this mode.
11.2.2 INPUT CAPTURE IN CPU IDLE
MODE
CPU Idle mode allows input capture module operation
with full functionality. In the CPU Idle mode, the Inter-
rupt mode selected by the ICI<1:0> bits is applicable,
as well as the 4:1 and 16:1 capture prescale settings
which are defined by c on trol bi ts ICM<2:0 >. This mod e
requires the selected timer to be enabled. Moreover,
the ICSIDL bit must be asserted to a logic ‘0’.
If the input capture module is defined as
ICM<2:0> = 111 in CPU Idle mode, the input capture
pin serves only as an external interrupt pin.
11.3 Input Capture Interr upts
The inpu t captur e channe ls have the a bility to generate
an interrupt based upon the selected number of cap-
ture event s. The selecti on number is set by co ntrol bits,
ICI<1:0> (ICxCON<6:5>).
Each chan nel provide s an interrupt flag (ICxI F) bit. The
respective capture channel interrupt flag is located in
the corresponding IFSx register.
Enabling an interrupt is accomplished via the respec-
tive capture channel interrupt enable (ICxIE) bit. The
capture interrupt enable bit is located in the
corresponding IEC Control register.

12.0 OUTPUT COMPARE MODULE
This sec tion desc ribes the ou tput comp are modu le and
associated operational modes. The features provided
by this module are useful in applications requiring oper-
ational modes , such as:
Generation of Variable Width Output Pulses
Pow er Fact or Correction
Figure 12-1 depicts a block diagram of the output
compare module.
The key operational features of the output compare
module include:
Timer2 and Timer3 Selection mode
Simple Output Compare Match mode
Dual Output Compare Match mode
Simple PWM mode
Output Compare During Sleep and Idle modes
Interrupt on Output Compare/PWM Event
These operating modes are determined by setting the
appropriate bits in the 16-bit OC1CON and OC2CON
registers . The dsPIC30F20 1 1/2012/ 3012/3013 devi ces
have 2 compare channels.
OCxRS and OCxR in Figure 12-1 represent the Dual
Compare registers. In the Dual Compare mode, the
OCxR register is used for the f irst comp are and O CxRS
is used for the second compare.

12.1 Timer 2 and Timer3 Selecti on Mode
Each output compare channel can select between one
of two 16-bit timers, Timer2 or Timer3.
The selection of the timers is controlled by the OCTSEL
bit (OCxCON<3> ). T im er2 is the de fault ti mer reso urce
for the output compare module.
12.2 Simple Output Compare Match
Mode
When control bits OCM<2:0> (OCxCON<2:0>) = 001,
010 or 011, the selected output compare channel is
configured for one of three simple Output Compare
Match modes:
Compare forces I/O pin low
Compare forces I/O pin high
Compare toggles I/O pin
The OCxR reg is ter i s us ed in th es e m ode s. Th e O C xR
register is loaded with a value and is compared to the
selected incrementing timer count. When a compare
occurs, o ne of these C ompare Match modes oc curs. If
the counter resets to zero before reaching the value in
OCxR, the state of the OCx pin remains unchanged.
12.3 Dual Output Compare Match Mode
When control bits OCM<2:0> (OCxCON<2:0>) = 100
or 101, the selec ted outp ut compare chan nel is co nfig-
ured for one of two Dual Output Compare modes,
which are:
Single Output Pulse mode
Conti nuous Output Pulse mode
12.3.1 SINGLE PULSE MODE
For the use r to confi gure the modul e for the ge ner ation
of a single output pulse, the following steps are
required (assuming timer is off):
Determine instruction cycle time TCY.
Calcu la te d es ired pulse w id t h v al ue bas ed on TCY.
Calcu late ti me to s tart pulse from ti mer st a rt valu e
of 0x0000.
Write pulse width start and stop times into OCxR
and OCxRS Compare registers (x denotes
channel 1, 2, ...,N).
Set Timer Period register to value equal to or
greater than value in OCxRS Compare register.
Set OCM<2:0> = 100.
Enable timer, TON (TxCON<15>) = 1.
To initiate another single pulse, issue another write to
set OCM<2:0> = 100.
12.3.2 CONTINUOUS PULSE MODE
For the use r to confi gure the modul e for the ge neratio n
of a continuous stream of output pulses, the following
steps are required:
Determine instruction cycle time TCY.
Calculate desired pulse value based on TCY.
Calcu late timer to st art pulse width from timer sta rt
value of 0x0000.
Write pulse width start and stop times into OCxR
and OCxRS (x denotes channel 1, 2, ...,N)
Compare registers, respectively.
Set Timer Period register to value equal to or
greater than value in OCxRS Compare register.
Set OCM<2:0> = 101.
Enable timer, TON (TxCON<15>) = 1.
12.4 Simple PWM Mode
When control bits OCM<2:0> (OCxCON<2:0>) = 110
or 111, the selec ted outp ut comp are c hannel is confi g-
ured for th e PWM mode of opera tion. When co nfigured
for the PWM mode of operation, OCxR is the main l atch
(read-only) and OCxRS is the secondary latch. This
enables glitchless PWM transitions.
The user must perform the following steps in order to
configure the output compare module for PWM
operation:
1. Set the PWM pe riod by writing to the appropriate
period register.
2. Set the PWM duty cy cle by writ ing to the OCxRS
register.
3. Configure the output compare module for PWM
operation.
4. Set the TMRx prescale value and enable the
Timer, TON (TxCON<15>) = 1.
12.4.1 INPUT PIN FAULT PROTECTION
FOR PWM
When control bits OCM<2:0> (OCxCON<2:0>) = 111,
the selected output compare channel is again config-
ured fo r the PWM mode of op eration with the add itional
feature of input Fault protection. While in this mode, if
a logic ‘0’ is detected on the OCF A/B pin, the respective
PWM output pin is placed in the high impedance input
state . The O CFLT bit (OCxCON <4>) in dicate s wheth er
a Faul t condition ha s occurred. Thi s state is mai ntaine d
until both of the following events have occurred:
The external Fault condition has been removed.
The PWM mode has been re-enabled by writing
to the appropriate control bits.

dsPIC30F2011/2012/3012/3013
12.4.2 PWM PERIOD
The PWM period is specified by writing to the PRx
register. The PWM period can be calculated using
Equation 12-1.
EQUATION 12-1:
PWM frequency is defined as 1/[PWM period].
When the selected TMRx is equal to its respective
period reg ister, PRx, the followi ng f our event s occ ur on
the next i ncrement cycle:
TMRx is clear e d.
The OCx pin is set.
- Exception 1: If PWM duty cycle is 0x0000,
the OCx pin remains low.
- Exception 2: If d uty cycl e is gr eater tha n PRx,
the pin remains high.
The PWM duty cycle is latched from OCxRS into
OCxR.
The corresponding timer interrupt flag is set.
See Figure 12-2 for key PWM period comparisons.
Timer3 is referred to in Figure 12-2 for clarity.
FIGURE 12-2: PWM OUTPUT TIMING
12.5 Output Compare Operation During
CPU Sleep Mode
When the CPU enters Sleep mode, all internal clocks
are stopped. Therefore, when the CPU enters the
Sleep s t ate, the outp ut c om p a re c ha nnel drives the pi n
to the active state that was observed prior to entering
the CPU Sleep state.
For exam ple, if the pin was hi gh when the CPU entere d
the Sleep state, the pin remains high. Likewise, if the
pin wa s low when the CPU entered th e Sleep st ate, th e
pin remains low. In either case, the output compare
module res um es operation w hen the dev ic e w a ke s u p.
12.6 Output Compare Operation During
CPU Idle Mode
When the CPU enters the Idle mode, the output
compare module can operate with full functionality.
The output compare channel operates during the CPU
Idle mode if the OCSIDL bit (OCxCON<13>) is at logic
0’ and the selected time base (Timer2 or Timer3) is
enabled and the TSIDL bit of the selected timer is set
to logic0’.
12.7 Output Compare Interrupts
The outpu t comp are channels have the abil ity to gener-
ate an interrupt on a compare match, for whichever
Match mode has been selected.
For all m odes exc ept the PWM mode, when a comp are
event occurs, the respective interrupt flag (OCxIF) is
asserted and an interrupt is generated if enabled. The
OCxIF bit is located in the corresponding IFS register
and must be cleared in software. The interrupt is
enabled via the respective compare interrupt enable
(OCxIE) bit located in the corresponding IEC Control
register.
For the PWM mode, when a n event occurs, the respec-
tive timer interrupt flag (T2IF or T3IF) is asserted and
an interrupt is generated if enabled. The IF bit is
located in the IFS0 register and must be cleared in soft-
ware. The interrupt is enabled via the respective timer
interrupt enable bit (T2IE or T3IE) located in the IEC0
Control register. The output compare interrupt flag is
never set during the PWM mode of operati on.

13.0 SPI MODULE
The Serial Peripheral Interface (SPI) module is a syn-
chronou s serial inte rface. It is usefu l for commun icating
with othe r periphera l devices, such as EEPROMs, shift
registers, display drivers and A/D converters, or other
microcontrollers. It is compatible with Motorola's SPI
and SIOP interfaces. The dsPIC30F2011/2012/3012/
3013 devices feature one SPI module, SPI1.
13.1 Operating Function Description
Figure 13-1 is a simplified block diagram of the SPI
module, which consists of a 16-bit shift register,
SPI1SR , used for shi fting dat a in and out , and a buf fer
register, SPI1BUF. Control register SPI1CON (not
shown ) conf igures the m odule. Additi onally, status re g-
ister SPI1STAT (not shown) indicates various status
conditions.
Four I/O pins comprise the serial interface:
SDI1 (serial data input)
SDO1 (serial data output)
SCK1 (shift clock input or output)
SS1 (active-low slave select).
In Master mode operation, SCK1 is a clock output. In
Slave mode, it is a clock input.
A series of eight (8) or sixteen (16) clock pulses shift
out bits from the SPI1SR to SDO1 pin and simulta-
neously shift in data from SDI1 pin. An interrupt is
generated when the transfer is complete and the
interrupt flag bit (SPI1IF) is set. This interrupt can be
disabled through the interrupt enable bit, SPI1IE.
The receive operation is double-buffered. When a com-
plete byte is received, it is transferred from SPI1SR to
SPI1BUF.
If the receive buffer is full when new data is being trans-
ferred from SPI1SR to SPI1BUF, the module will set the
SPIROV bit i ndicating an overflow cond ition. The trans -
fer of the data from SPI1SR to SPI1BUF is not com-
pleted and the new data is lost. The module will not
resp ond to SC L transi tion s while S PIROV is ‘1’, effec-
tively disabling the module until SPI1BUF is read by
user softw are .
Transmit writes are also double-buffered. The user
writes to SPI1BUF. When the master or slave transfer
is completed, the contents of the shift register
(SPI1SR) are m ov ed to the re cei ve buffer. If any trans-
mit da ta has been wr itten t o the bu ffer register, the co n-
tents of the t ran smit bu ffer ar e mov ed t o SPI 1SR. T he
receive d data is thus placed in SPI1BUF and the trans-
mit data in SPI1SR is ready for the next transfer.

Figure 13-2 depicts the a master/slave connection
between two processors. In Master mode, the clock is
generated by prescaling the system clock. Data is
tran smitte d as soon a s a val ue is wr itten to SPI1B UF.
The interrupt is generated at the middle of the transfer
of the last bit.
In Slave mode, data is transmitted and received as
external clock pulses appear on SCK. Again, the inter-
rupt is generated when the last bit is latched. If SS1
control i s enabled , then transm ission and recepti on are
enabled only w hen SS1 = lo w . The SDO1 output wil l be
disabled in SS1 mode with SS1 high.
The clock provided to the module is (FOSC/4). This
clock is then prescaled by the primary (PPRE<1:0>)
and the secondary (SPRE<2:0>) prescale factors. The
CKE bit determines whether transmit occurs on transi-
tion from active clock state to Idle clock state, or vice
versa. The CKP bit selects the Idle state (high or low)
for the clock.
13.1.1 WORD AND BYTE
COMMUNICATION
A control bit, MODE16 (SPI1CON<10>), allows the
module to communicate in either 16-bit or 8-bit mode.
16-bit operation is identical to 8-bit operation except
that the number of bits transmitted is 16 instead of 8.
The user software must disable the module prior to
changing the MODE16 bit. The SPI module is reset
when the MODE16 bit is changed by the user.
A basic dif ference betwee n 8-bit and 16-bit operat ion is
that the data is transmitted out of bit 7 of the SPI1SR
for 8-bit operation, and data is transmitted out of bit 15
of the SPI1SR for 16-bit op eration. In both modes, data
is shifted into bit 0 of the SPI1SR.
13.1.2 SDO1 DISABLE
A control bit , DISSDO, is provided to the SPI1CON reg-
ister to allow the SDO1 output to be disabled. This will
allow the SPI module to be connected in an input only
configuration. SDO1 can also be used for general
purpose I/O.
13.2 Framed SPI Support
The module supports a basic framed SPI protocol in
Master or Slave mode. The control bit, FRMEN,
enables fram ed SPI sup port a nd c auses the SS 1 pin to
perform the Frame Synchronization Pulse (FSYNC)
function. The control bit, SPIFSD, determines whether
the SS1 pin is an input or an output (i.e., whether the
module rec ei ves o r ge nera tes th e Frame Sync hron iz a-
tion Puls e). Th e fra me pul se i s an ac tiv e-h igh pul se for
a single SPI clock cycle. When Frame Synchronization
is enabled, the data transmission starts only on the
subsequent transmit edge of the SPI clock.

13.3 Slave Select Synchroni zation
The SS1 pin allows a Synchronous Slave mode. The
SPI must be configured in SPI Slave mode with SS1
pin control enabled (SSEN = 1). When t he SS1 pin is
low, transmission and reception are enabled and the
SDOx pin is driven. When SS1 pin goes high, the
SDOx pin is no longer driven. Also, the SPI module is
resynchronized, and all counters/control circuitry are
reset. Therefore, when the SS1 pin is asserted low
again, transmission/reception will begin at the MSb
even if SS1 had been de-asserted in the middle of a
transmit/receive.
13.4 SPI Operation During CPU Sleep
Mode
During Sleep mode, the SPI module is shut down. If th e
CPU enters Sleep mode while an SPI transaction is in
progress, then the transmission and reception is
aborted.
The transmitter and receiver will stop in Sleep mode.
Howeve r , regi ster conten ts are not af fected by entering
or exiting Sleep mode.
13.5 SPI Operation During CPU Idle
Mode
When the device enters Idle mode, all clock sources
remain functional. The SPISIDL bit (SPI1STAT<13>)
select s if the SPI module will sto p or continue on idle. If
SPISIDL = 0, t he module will contin ue to op erate w hen
the CPU enters Idle mode. If SPISIDL = 1, the module
will stop when the CPU enters Idle mode.

14.0 I2C™ MODULE
The Inter-Integrated Circuit (I2CTM) module provides
complete hardware support for both Slave and Multi-
Master modes of the I2C serial communication
standard, with a 16-bit interface.
This module offers the following key features:
•I
2C interface supporting both master and slave
operation.
•I
2C Slave mode supports 7 and 10-bit address.
•I
2C Master mode supports 7 and 10-bit address.
•I
2C port allows bidirectional transfers between
master and slav es.
Serial clock synchronization for I2C port can be
used as a ha ndshake mechanis m to suspen d and
resume serial transfer (SCLREL control).
•I
2C supports multi-master operation; detects bus
collision and will arbitrate accordingly.
14.1 Operating Function Description
The hardw are fully imple ments al l the master an d slave
functions of the I2C Standard and Fast mode
specifications, as well as 7 and 10-bit addressing.
Thus, the I2C module can operate either as a slave or
a master on an I2C bus.
14.1.1 VARIOUS I2C MODES
The following types of I2C operation are supported:
•I
2C slave operation with 7-bit address
•I
2C slave operation with 10-bit address
•I
2C master operation with 7 or 10-bit address
See the I2C programmer’s model (Figure 14-1).
14.1.2 PIN CONFIGURATION IN I2C MODE
I2C has a 2-pin interface: the SCL pin is clock and the
SDA pin is data.
14.1.3 I2C REGISTERS
I2CCON and I2C STAT are control and s ta tus reg isters ,
respect ively . Th e I2CCON register is readable an d writ-
able. The lower 6 bits of I2CSTAT are read-only. The
remaining bits of the I2CSTAT are read/write.
I2CRSR is the shift register used for shifting data,
whereas I2CRCV is the buffer register to which data
bytes are written, or from which data bytes are read.
I2CRCV is the receive buffer as shown in Figure 14-1.
I2CTRN is the transmit register to which bytes are
written during a transmit operation, as shown in
Figure 14-2.
The I2C ADD registe r holds the slave ad dress. A Status
bit, ADD10, indicates 10-bit Address mode. The
I2CBRG acts as the Baud Rate Generator reload
value.
In receive operations, I2CRSR and I2CRCV together
form a double-buffered receiver. When I2CRSR
receives a complete byte, it is transferred to I2CRCV
and an interrupt pulse is generated. During
transmission, the I2CTRN is not double-buffered.

14.2 I2C Module Addresses
The I2CADD register contains the Slave mode
addresses. The register is a 10-bit register.
If the A10M bit (I2CCON<10>) is ‘0’, the address is
inter prete d by the mo dul e as a 7 - bit add ress . When an
address is received, it is compared to the 7 LSb of the
I2CADD register.
If the A10M bit is ‘1’, the address is assumed to be a
10-bit address. When an address is received, it will be
compared with the binary value ‘11110 A9 A8’ (where
A9 and A8 are t wo Mo st Si gn i f ic ant b its of I2 C AD D) . I f
that valu e m atc hes , th e ne xt ad dre ss will be c om p are d
with the Least Significant 8 bits of I2CADD, as specified
in the 10-bit addressing protocol.
The 7-bit I2C Slave Addresses supported by the
dsPIC30F are shown in Table 14-1.
TABLE 14-1: 7-BIT I2C™ SLAVE
ADDRESSES
14.3 I2C 7-bit Slave Mode Operation
Once enabled (I2CEN = 1), the slave module will wait
for a S t art bit to occur (i.e., the I2C module is ‘I dle’). Fol-
lowin g t he det ection of a St art bit , 8 bi ts are s hif ted into
I2CRSR and the address is compared against
I2CADD. In 7-bit mode (A10M = 0), bits I2CADD<6:0>
are compared against I2CRSR<7:1> and I2CRSR<0>
is the R_W bit. All inco ming bit s are sampl ed on the ris-
ing edge of SCL.
If an address match occurs, an acknowledgement will
be sent, and the slave event interrupt flag (SI2CIF) is
set on the falling edge of the ninth (ACK) bit. The
address match does not affect the contents of the
I2CRCV buffer or the RBF bit.
14.3.1 SLAVE TRANSMISSION
If the R_W bit received is a ‘1’, then the serial port will
go into Transmit mode. It wil l send ACK on the nin th bit
and then hold SCL to ‘0’ un til the CPU responds by writ-
ing to I2C TRN. SCL is rele ased by settin g the SCLREL
bit, and 8 bits of data are shifted out. Data bits are
shifted out on the fa lling edge of SCL, s uch that SDA i s
valid during SCL high. The interrupt pulse is sent on the
falling edge of the ninth clock pulse, regardless of the
status of the ACK received from the master.
14.3.2 SL AVE RECE P TION
If the R_W bit received is a ‘0’ during an address
match, then Receive mode is initiated. Incoming bits
are sa mpl ed on the risi ng ed ge of SCL . After 8 bi t s are
received, if I2CRCV is not full or I2COV is not set,
I2CRSR is transferred to I2CRCV. ACK is sent on the
ninth clock.
If the RBF flag is set, indicating that I2CRCV is still
holding data from a pre vious operati on (RBF = 1), the n
ACK is not sent; however, the interrupt pulse is gener-
ated. In the case of an overflow, the contents of the
I2CRSR are not loaded into the I2CRCV.
14.4 I2C 10-bit Slave Mode Operation
In 10-bit mode, the basic receive and transmit opera-
tions are the same as in the 7-bit mode. However, the
criteria for address match is more complex.
The I2C specification dictates that a slave must be
address ed for a write operatio n with two ad dress byte s
following a Start bit.
The A10M bit is a control bit that signifies that the
address in I2CADD is a 10-bit address rather than a 7-bit
address. The address detection protocol for the first byte
of a message address is identical for 7-bit and 10-bit
mess ag es , b ut the bit s being co m p a r ed ar e different.
I2CADD holds the entire 10-bit address. Upon receiv-
ing an address following a Start bit, I2CRSR <7:3> is
compared against a literal ‘11110’ (the default 10-bit
address) and I2CRSR<2:1> are compared against
I2CADD<9:8>. If a match occurs and if R_W = 0, the
interrupt pu lse is sent. Th e ADD10 bit will be cleare d to
indicate a partial address match. If a match fails or
R_W = 1, the ADD10 bit is cleared and the module
returns to the Idle state.
The low byte of the address is then received and com-
pared with I2CADD<7:0>. If an address match occurs,
the interrupt pulse is generated and the ADD10 bit is
set, indicating a complete 10-bit address match. If an
address match did not occur, the ADD10 bit is cleared
and the module returns to the Idle state.
0x00 General call address or start byte
0x01-0x03 Reserved
0x04-0x 07 Hs-mo de Ma ste r codes
0x04-0x77 Valid 7-bit addresses
0x78-0x7b Valid 10-bit addresses (lower 7
bits)
0x7c-0x7f Reserved
Note: The I2CRCV will be loaded if the I2COV
bit = 1 and the RBF flag = 0. In this case,
a read of the I2CRCV was performed but
the user did not clear the state of the
I2COV bit before the next receive
occurred. The acknowledgement is not
sent (ACK = 1) and the I2CRCV is
updated.

DS70139E-page 96 © 2006 Microchip Technology Inc.
14.4.1 10-BIT MODE SLAVE
TRANSMISSION
Once a slave is addressed in this fashion with the full
10-bit address (we will refer to this state as
“PRIOR_ADDR_MATCH”), the master can begin
sending data bytes for a slave reception operation.
14.4.2 10-BIT MODE SLAVE RECEPTION
Once ad dress ed, the ma ster ca n genera te a Rep eated
Start, reset the high byte of the address and set the
R_W bit without generating a Stop bit, thus initiating a
slave tran sm it ope ratio n.
14.5 Automatic Clock Stretch
In the Slave modes, the module can synchronize buffer
reads and write to the master device by clock stretching.
14.5.1 TRAN SMI T CLOCK STRETCHING
Both 10-bit and 7-bit Transmit modes implement clock
stretching by asserting the SCLREL bit after the falling
edge of the ninth cloc k, if the TBF bit is c leared, indic at-
ing the buffer is empty.
In Slave Transmit modes, clock stretching is always
performed irrespective of the STREN bit.
Clock synchronization takes place following the ninth
clock of the transmit sequence. If the device samples
an AC K on the falling edge of the ninth clock and if the
TBF bit is still clear, then the SCLREL bit is automati-
cally cleared. The SCLREL being cleared to ‘0’ will
assert the SCL line low. The user s ISR must set the
SCLRE L bit bef ore transmis sion is allowed to cont inue.
By holding the SCL line low, the user has time to ser-
vice the ISR and load the contents of the I2CTRN
before the master device can initiate another transmit
sequence.
14.5.2 REC EIVE CLOCK STRETCHING
The STREN bit in the I2CCON register can be used to
enable clock stretching in Slave Receive mode. When
the STR EN bit is s et, the SCL p in will be held low at the
end of each data receive sequence.
14.5.3 CLOCK STRETCHING DURING
7-BIT AD DRES SIN G (S TR EN = 1)
When the S TREN bit is set in Slave R eceive mode , the
SCL lin e is hel d low when th e buf fer register i s full . The
method for stretching the SCL output is the same for
both 7 and 10-bit addressing modes.
Clock stretch ing ta kes pla ce follo wing th e ninth clock of
the receive sequence. On the falling edge of the ninth
clock at the end of the AC K sequence, if the RBF bit is
set, the SCLREL bit is automatically cleared, forcing
the SCL o utput to be held l ow. The user’s ISR must s et
the SCLREL bit before reception is allowed to continue.
By hol ding th e SCL line low, the us er has time to ser-
vice the ISR and read the contents of the I2CRCV
before the master device can initiate another receive
sequence. This will prevent buffer overruns from
occurring.
14.5.4 CLOCK STRETCHING DURING
10-BIT ADDRESSING (STREN = 1)
Clock stretching takes place automatically during the
addressing sequence. Because this module has a
register for the entire address, it is not necessary for
the protocol to wait for the address to be updated.
After the address phase is complete, clock stretching
will occur on each data receive or transmi t sequence as
was described earlier.
14.6 Software Controlled Clock
Stretching (STREN = 1)
When the STREN bit is ‘1’, the SCLREL bit may be
cleared by software to allow software to control the
clock stretching. The logic will synchronize writes to the
SCLREL bit with the SCL clock. Clearing the SCLREL
bit will not assert the SCL output until the module
detects a falling edge on the SCL output and SCL is
sampled low. If the SCLREL bit is cleared by the user
while the SCL line has been sample d low, the SCL out-
put will be asserted (held low). The SCL output will
remain low until the SCLREL bit is set, and all other
devices on the I2C bus have de-asserted SCL. This
ens ures that a write to t he SCLR EL bit will not viol ate
the minimum high time requirement for SCL.
If the STREN bit is ‘0’, a software write to the SCLREL
bit will be disregarded and have no effect on the
SCLREL bit.
Note 1: If the user loads the contents of I2CTRN,
setting the TBF bit before the fallin g edge
of the n int h c lo ck , th e SC LREL bit w il l n ot
be cleared and clock stretching will not
occur.
2: The SCLREL bit can be set in software,
regardless of the state of the TBF bit.
Note 1: If the user reads the contents of the
I2CRCV, clearing the RBF bit before the
falling edge of the ninth clock, the
SCLREL bit will not be cleared and clock
stretching will not occur.
2: The SCLREL bit can be set in software
regardles s of the state of the RBF bit. The
user should be careful to clear the RBF bit
in the ISR before the next receive
sequence in order to prevent an overflow
condition.

dsPIC30F2011/2012/3012/3013
14.7 Interrupts
The I2C module generates two interrupt flags, MI2CIF
(I2C Master I nterrupt Flag) an d SI2CIF (I2C Slav e Inter-
rupt Flag). The MI2CIF interrupt flag is activated on
completion of a master message event. The SI2CIF
interrupt flag is activated on detection of a message
directed to the slave.
14.8 Slope Control
The I2C standard requires slope control on the SDA
and SCL signals for Fast mode (400 kHz). The control
bit, DISSLW , enables the us er to disable slew rate con-
trol if desired. It is necessary to disable the slew rate
control for 1 MHz mode.
14.9 IPMI Support
The con trol bit, IPM IEN, enabl es the modul e to supp ort
Intelligent Peripheral Management Interface (IPMI).
When this bit is set, the module ac ce pts and ac t s upo n
all addres ses .
14.10 General Call Address Support
The general call address can address all devices.
When this address is used, all devices should, in
theor y, respond with an ackno w led gem en t.
The general call address is one of eight addresses
reserved for specific purposes by the I2C protocol. It
consists of all ‘0’s with R_W = 0.
The general call address is recognized when the Gen-
eral Call Enable (GCEN) bit is set (I2CCON<7> = 1).
Following a Start bit detection, 8 bits are shifted into
I2CRSR and the address is compared with I2CADD,
and is also compared with the general call address
which is fixed in hardware.
If a gen eral cal l addre ss matc h occurs, the I2CRS R is
transferred to the I2CRCV after the eighth clock, the
RBF flag is set and on the falling edge of the ninth bit
(ACK bit), the master event interrupt flag (MI2CIF) is
set.
When the i nte rrupt is serviced, the s ou rce f or th e int er-
rupt can be checked by reading the contents of the
I2CRCV to determine if the address was device
specific or a general call address.
14.11 I2C Master Support
As a master device, six operations are supported:
Assert a Start condition on SDA and SCL.
Assert a Restart condition on SDA and SCL.
Write to the I2CTRN register initiating
transmission of data/address.
Generate a Stop condition on SDA and SCL.
Config ure the I2C port to receive data.
Generate an ACK condition at the end of a
received byte of data.
14.12 I2C Master Operation
The master device generates all of the serial clock
pulses and the Start and Stop conditions. A transfer is
ended with a Stop condition or with a Repeated Start
condition. Since the Repeated Start condition is also
the begi nning of the next seria l transfer, the I2C bus will
not be released.
In Master Transmitter mode, serial data is output
through SDA, while SCL outputs the serial clock. The
first byte transmitted contains the slave address of the
receiving device (7 bits) and the data direction bit. In
this ca se, the da ta direc tion bit (R_ W) is logi c ‘0’. Serial
data is transmitted 8 bits at a time. After each byte is
transmitted , an ACK bit i s received . S t art and Stop con-
ditions are output to indicat e the beginn ing and the en d
of a serial transfer.
In Master Rec eive mode, the firs t byte transmitte d con-
tains the slave address of the transmitting device
(7 bits) and the data direction bit. In this case, the data
directio n bit (R_W) is lo gic ‘1’. Thus, the first byte trans -
mitted is a 7-b it slave a ddre ss , followed b y a ‘ 1’ to ind i-
cate re ceive bi t. Serial data is rece ived via SD A while
SCL outputs the serial clock. Serial data is received
8 bits at a time . After each by te is re cei ve d, a n ACK bit
is transmitted. Start and Stop conditions indicate the
beginning and end of transmission.
14.12.1 I2C MASTER TRANSMI S SION
T ransmission of a data byte, a 7-bit address, or the sec-
ond half of a 10-b it addre ss, is acc ompl ished by simpl y
writing a value to I2CTRN register. The user should
only write to I2CTRN when the module is in a WAIT
state . This actio n will set th e Buf fer Full Flag (TBF ) and
allow the Baud Rate Generator to begin counting and
start the next transmission. Each bit of address/data
will be shifted out onto the SDA pin after the falling
edge of SCL is asserted. The Transmit Status Flag,
TRSTAT (I2CSTAT<14>), indicates that a master
transmit is in progress.
dsPIC30F2011/2012/3012/3013
DS70139E-page 98 © 2006 Microchip Technology Inc.
14.12.2 I2C MASTER RECEPTION
Master mode recepti on is enab led by progra mmin g the
Receive Enable bit, RCEN (I2CCON<3>). The I2C
module must be Idle before the RCEN bit is set, other-
wise the RCEN bit will be disregarded. The Baud Rate
Generator begins counting and on each rollover, the
state of the SCL pin ACK and data are shifted into the
I2CRSR on the rising edge of each clock.
14.12.3 BAUD RATE GENERATOR
In I2C Master mode, the reload value for the BRG is
located in the I2CBRG register. When the BRG is
loaded w ith th is v alu e, the BRG c ou nt s d own to ‘0’ and
stop s until anothe r reload has take n place. If clock arb i-
tration i s taking place, for instance , the BRG is reloaded
when the SCL pin is sampled high.
As per the I2C standard, FSCK may be 100 kHz or
400 kHz. However, the user can specify any baud rate
up to 1 MHz. I2CBRG values of ‘0’ or ‘1’ are illegal.
EQUATION 14-1: SERIAL C LOCK RATE
14.12.4 CLOCK ARBITRATION
Clock arbitration occurs when the master de-asserts
the SCL pin (SCL allowed to float high) during any
receive, transmit, or Restart/Stop condition. When the
SCL pin is allowed to float high, the Baud Rate Gener-
ator (BRG) is suspended from counting until the SCL
pin is ac tually sam pled high. When the SCL pin is sam -
pled high, the Baud Rate Generator is reloaded with
the contents of I2CBRG and begins counting. This
ensures that the SCL high time will always be at least
one BRG rollover count in the event that the clock is
held low by an external device.
14.12.5 MULTI-MASTER COMMUNICATION,
BUS COLLISION, AND BUS
ARBITRATION
Multi-m aster operation support is achieved by bus arbi-
tration. When the master outputs address/data bits
onto the SDA pin, arbitration takes place when the
master outputs a ‘1 on SDA by letting SDA float high
whil e another mas ter asser ts a ‘0’. When the SCL pin
floats high, data should be stable. If the expected data
on SDA is a ‘1’ and the data sampled on the SDA
pin = 0, then a bus collision has taken place. The
master will set the MI2CIF pulse and reset the master
portion of the I2C port to its Idle state.
If a transmit was in progress when the bus collision
occurred, the transmission is halted, the TBF flag is
cleared , the SDA a nd SCL lin es are d e-as se rted and a
value can now be written to I2CTRN. When the user
services the I2C master event Interrupt Service Rou-
tine, if the I2C bu s i s free (i.e., the P bit is s et), the us er
can resume communication by asserting a Start
condition.
If a Start, Restart, Stop or Acknowledge condition was
in progres s when the bus co lli si on o cc urre d, th e c ond i-
tion is aborted, the SDA and SCL lines are de-asserted,
and the respective control bits in the I2CCON register
are cleared to ‘0’. Whe n t h e us er se rv ic es th e bu s c ol -
lision Interrupt Service Routine, and if the I2C bus is
free, the user can resume co mm uni ca tio n by as se rting
a St art conditi on .
The master will continue to monitor the SDA and SCL
pins, and if a Stop condition occurs, the MI2CIF bit will
be set.
A write to the I2CTR N will start the trans mission of dat a
at the first data bit regardless of where the transmitter
left off when bus collision occurred.
In a multi-maste r en vi ronm en t, th e i nte rrup t ge nera tio n
on the d etecti on of St art a nd Stop conditio ns al lows the
determination of when the bus is free. Control of t he I2C
bus can be taken when the P bit is set in the I2CSTAT
register, or the bus is Idle and the S and P bits are
cleared.
14.13 I2C Module Operation During CPU
Sleep and Idle Modes
14.13.1 I2C OPERATION DURING CPU
SLEE P MOD E
When the device enters Sleep mode, all clock sources
to the module are shut down and stay at logic 0’. If
Sleep occurs in the middle of a transmission and the
state machine is partially into a transmission as the
clocks s top, the n the tra nsmiss ion is ab orted. Si milarl y,
if Sleep occurs in the middle of a reception, then the
reception is aborted.
14.13.2 I2C OPERATION DURING CPU IDLE
MODE
For the I2C, the I2CSIDL bit selects if the module will
stop on Idle or continue on Idle. If I2CSIDL = 0, the
module will continue operation on assertion of the Idle
mode. If I2CSIDL = 1, the module w ill s top on Idle.

15.2 Enabling and Setting Up UART
15.2.1 ENABLING THE UART
The UART module is enabled by setting the UARTEN
bit in the UxMODE register (where x = 1 or 2). Once
enabled , the UxTX and UxRX pins are configured as an
output and an input respectively, overriding the TRIS
and LAT regi ster bit setting s for the corres pondin g I/O
port pins. The UxTX pin is at logic ‘1’ when no
transmission is taking place.
15.2.2 DISABLING THE UART
The UAR T module is di sabled by cle aring the UAR TEN
bit in the UxMODE register. This is the default state
after any Reset. If the UART is disabled, all I/O pins
operate as port pins under the control of the LAT and
TRIS bits of the corresponding port pins.
Disab ling the UAR T module reset s the buf fers to empty
states. Any data characters in the buffers are lost and
the baud rate counter is reset.
All error and status flags associated with the UART
module are reset when the module is disabled. The
URXDA, OERR, FERR, PERR, UTXEN, UTXBRK and
UTXBF bits are cleared, whereas RIDLE and TRMT
are set. Other control bits, including ADDEN,
URXISEL<1:0>, UTXISEL, as well as the UxMODE
and UxBRG registers, are not affected.
Clearing the UARTEN bit while the UART is active will
abort all pending transmissions and receptions and
reset the module as defined above. Re-enabling the
UART will restart the UART in the same configuration.
15.2.3 AL TERNA TE I/O
The alternate I/O function is enabled by setting the
ALTIO bit (UxMODE<10>). If ALTIO = 1, the UxATX
and UxARX pins (alternate transmit and alternate
receive pins, respectively) are used by the UART mod-
ule instead of the UxTX and UxRX pins. If ALTIO = 0,
the UxTX and UxRX pins are used by the UART
module.
15.2.4 SETTING UP DATA, PARITY AND
STOP BIT SELECTIONS
Control bits PDSEL<1:0> in the UxMODE register are
used to select the data length and parity used in the
transmission. The data length may either be 8 bits with
even, odd or no parity, or 9 bits with no parity.
The STSEL bit determines whether one or two S top bit s
will be used during data transmissi on.
The defa ult (powe r-on) settin g of the UA RT is 8 bits, n o
parity and 1 Stop bit (typically represented as 8, N, 1).
15.3 Transmitting Data
15.3.1 TRANSMITTING IN 8-BIT DATA
MODE
The following steps must be performed in order to
transmit 8-bit data:
1. Set up the UART:
First, the data length, parity and number of Stop
bits must be selected. Then, the transmit and
receive interrupt enable and priority bits are
setup in the UxMODE and UxSTA registers.
Also, the appropriate baud rate value must be
written to the UxBRG register.
2. Enable the UART by setting the UARTEN bit
(UxMODE<15>).
3. Set the UTXEN bit (UxSTA<10>), thereby
enabling a transmission.
4. Write the byte to be t ransmitted to the lower byte
of UxTXREG. The value wi ll be transferred to the
Transmit Shift register (UxTSR) immediately
and the serial bit stream will start shifting out
during the next rising edge of the baud clock.
Alternatively, the data byte may be written while
UTXEN = 0, following which, the user may set
UTXEN. This will cause the serial bit stream to
begin immediately because the baud clock will
start from a cleared state.
5. A transmit interrupt will be generated, depend-
ing on the value of the interrupt control bit
UTXISEL (UxSTA<15>).
15.3.2 TRANSMITTING IN 9-BIT DATA
MODE
The sequence of steps involved in the transmission of
9-bit data is similar to 8-bit transmission, except that a
16-bit data word (of which the upper 7 bits are always
clear) must be written to the UxTXREG register.
15.3.3 TRANSMIT BUFFER (UXTXB)
The transmit buffer is 9 bits wide and 4 characters
deep. Including the Transmit Shift register (UxTSR),
the user effectively has a 5-deep FIFO (First-In, First-
Out) buffer. The UTXBF bit (UxSTA<9>) indicates
whether the transmit buffer is full.
If a user attempts to write to a full buffer, the new data
will not be ac c epte d into the FIFO and no dat a shift w il l
occur within the buffer. This enables recovery from a
buffer overrun condition.
The FIFO is reset during any device Reset, but is not
affected when the device enters or wakes up from a
Power Saving mode.
dsPIC30F2011/2012/3012/3013
DS70139E-page 104 © 2006 Microchip Technology Inc.
15.3.4 TRANSMIT INTERRUPT
The transmit interrupt flag (U1TXIF or U2TXIF) is
located in the corresponding interrupt flag register.
The transmitter generates an edge to set the UxTXIF
bit. The cond itio n for gene ratin g the in terru pt depe nds
on the UTXISEL control bit:
a) If UTXISEL = 0, an interrupt is generated when
a word is transferred from the transmit buffer to
the T ransmit Shi ft registe r (UxTSR). This means
that the transmit buffer has at least one empty
word.
b) If UTXISEL = 1, an interrupt is generated when
a word is transferred from the transmit buffer to
the Transmit Shift register (UxTSR) and the
transmit buffer is empty.
Switching between the two Interrupt modes during
operation is possible and sometimes offers more
flexibility.
15.3.5 TRANSMIT BREAK
Setting the UTXBRK bit (UxSTA<11>) will cause the
UxTX line to be driven to logic0’. The UTXBRK bit
overrides all transmission activity. Therefore, the user
should generally wait for the transmitter to be Idle
before setting UTXBRK.
To send a Break character , the UTXBRK bit must b e set
by soft ware and must re main set for a mi nimum of 13
baud clock cycles. The UTXBRK bit is then cleared by
software to generate Stop bits. The user must wait for
a duration of at least one or two baud clock cycles in
order to ensure a valid Stop bit(s) before reloading the
UxTX B, or s tar t i ng o t he r t r an sm itt e r ac ti v it y. Transmis -
sion of a Break ch arac te r doe s no t ge nera te a transmit
interrupt.
15.4 Receiving Data
15.4.1 RECEIVING IN 8-BIT OR 9-BIT
DATA MODE
The following steps must be performed while receiving
8-bit or 9-bit data:
1. Set up the UART (see Section 15.3.1 “Trans-
mitting in 8-bit data mode”).
2. Enable the UART (see Section 15.3.1 “Trans-
mitting in 8-bit data mode”).
3. A receive interrupt will be generated when one
or more data words have been received,
depending on the receive interrupt settings
specified by the URXISEL bits (UxSTA<7:6>).
4. Read the OERR bit to determine if an overrun
error has occ urred. The OERR bit must be reset
in software.
5. Read the received data from UxRXREG. The act
of reading UxRXREG will move the next word to
the top of the receive FIFO, and the PERR and
FER R values will be update d.
15.4.2 RECEIVE BUFFER (UXRXB)
The receive buffer is 4 words deep. Including the
Receive Shift register (UxRSR), the user effectively
has a 5-word deep FIFO buffer.
URXDA (UxSTA<0>) = 1 indicates that the receive
buffer has data available. URXDA = 0 implies that the
buffer is empty. If a user attempts to read an empty
buffer, the old values in the buffer will be read and no
data shift will occur within the FIFO.
The FIFO is reset during any device Reset. It is not
affected when the device enters or wakes up from a
Power Saving mode.
15.4.3 RECEIVE INTERRUPT
The receive interrupt flag (U1RXIF or U2RXIF) can be
read from the c orresp onding interru pt fla g register. The
interrupt flag is set by an edge generated by the
rece iver. The cond iti on f or se tti ng t he re ceiv e int err upt
flag depends on the settings specified by the
URXISEL<1:0> (UxSTA<7:6>) control bits.
a) If URXISEL<1:0> = 00 or 01, an interrup t is gen-
erated every time a data word is transferred
from the Receive Shift register (UxRSR) to the
receive buffer. There may be one or more
charact ers in the receive buffer.
b) If URXISEL<1:0> = 10, an interrupt is generated
when a word is transferred from the Receive Shift
register (UxRSR) to the receive buffer , which as a
result of the transfer, contains 3 characters.
c) If URXISEL<1:0> = 11, an interrupt is set when
a word is transf erred from th e Receive Shift reg-
ister (UxRSR) to the receive buffer, which as a
result of the transfe r, conta ins 4 c ha rac ters (i.e .,
becomes full).
Switching between the Interrupt modes during opera-
tion is possible, though generally not advisable during
normal operation.
15.5 Reception Error Handling
15.5.1 RECEIVE BUFFER OVERRUN
ERROR (OERR BIT)
The OERR bit (UxSTA<1>) is set if all of the following
conditions occur:
a) The receive buffer is full.
b) The Receive Shift register is full, but unable to
transfer the character to the receive buffer.
c) The Stop bit of the character in the UxRSR is
detected, indicating that the UxRSR needs to
transfer the character to the buffer.
Once OERR is se t, no furthe r dat a is s hif ted in UxRSR
(until the OERR bit is cleared in software or a Reset
occurs). The data held in UxRSR and UxRXREG
remains val id.
© 2006 Microchip Technology Inc. DS70139E-page 105
dsPIC30F2011/2012/3012/3013
15.5.2 FRAMING ERROR (FERR)
The FERR bit (UxSTA<2>) is set if a ‘0’ is detected
instead of a Stop bit. If two Stop bits are selected, both
Stop bits must be ‘1’, otherwise FERR will be set. The
read-only FERR bit is buffered along with the received
data. It is cleared on any Reset.
15.5.3 PARITY ERROR (PERR)
The PERR bit (UxSTA<3>) is set if the parity of the
received word is incorrect. This error bit is applicable
only if a Parity mode (odd or even) is selected. The
read-only PERR bit is buffered along with the received
data bytes. It is cleared on any Reset.
15.5.4 IDLE STATUS
When the receiver is active (i.e., between the initial
detecti on of the Start bit and the comp letion of the Sto p
bit), the RIDLE bit (UxST A<4>) is ‘0 . Between the com-
pletion of the Stop bit and dete ction of the next S tart bit,
the RIDLE bit is ‘1’, indicating that the UART is Idle.
15.5.5 R EC EIV E BRE AK
The receiver will count and expect a certain number of
bit times based on the values programmed in the
PDSEL (UxMODE<2:1>) and STSEL (UxMODE<0>)
bits.
If the break is longer than 13 bit times, the reception is
considered complete after the number of bit times
specif ied by PDSEL and STSEL. The URXDA bit is se t,
FERR is set, zeros are loaded into the receive FIFO,
interrupts are generated if appropriate and the RIDLE
bit is set.
When the module receiv es a lo ng b r ea k s ign al a nd th e
receive r has detected the S t art bit, the dat a bits and the
invalid Stop bit (which sets the FERR), the receiver
must wai t for a val id Sto p bit before looki ng for the next
Start bit . It cannot assu me that the br eak conditi on on
the line is the next Start bit.
Break is reg arded as a characte r containin g all ‘0’s with
the FERR bit set. The Break character is loaded into
the buf fer . No further reception can occur until a S top bit
is received. Note that RIDLE goes high when the Stop
bit has not yet been received.
15.6 Address Detect Mode
Setting the ADDEN bit (UxSTA<5>) enables this spe-
cial mode in which a 9th bit (URX8) value of ‘1’ identi-
fies the rec ei ve d wo rd a s a n a ddress, rathe r th an data.
This m ode is o nly a pplicable for 9-bi t d ata comm un ic a-
tion. The URXISEL control bit does not have any
impact on interrupt generation in this mode since an
interrupt (if enabled) will be generated every time the
received word has the 9th bit set.
15.7 Loopback Mode
Setting the LPBACK bit enables this special mode in
which the UxTX pin is int ernally conne cted to the UxRX
pin. When configured for the Loopback mode, the
UxRX pin is disconnected from the internal UART
receive logic. However, the UxTX pin still functions as
in a normal operation.
To select this mode:
a) Configure UART for desired mode of operation.
b) Set LPBACK = 1 to enable Loopback mode.
c) Enable tran sm is si on as def ine d in Section 15.3
“Transmitting Data”.
15.8 Baud Rate Generator
The UART has a 16-bit Baud Rate Generator to allow
maximu m fl exib ilit y in b aud r ate ge nera tio n. Th e Baud
Rate Generator register (UxBRG) is readable and
writable. The baud rate is computed as follows:
BRG = 16-bit value held in UxBRG register
(0 through 65535)
FCY = Instruction Clock Rate (1/TCY)
The baud rate is given by Equation 15-1.
EQUATION 15-1: BAUD RATE
Therefore, the maximum baud rate possible is:
FCY /16 (if BRG = 0),
and the minimum baud rate possible is:
FCY / (16* 65536).
With a full 16-bit Baud Rate Generator at 30 MIPS
operation, the minimum baud rate achievable is
28.5 bps.
Baud Rate = FCY / (16*(BRG+1))
dsPIC30F2011/2012/3012/3013
DS70139E-page 106 © 2006 Microchip Technology Inc.
15.9 Auto-Baud Support
To allow the system to determine baud rates of
received characters, the input can be optionally linked
to a selec ted cap ture inpu t (IC1 for U ART1 and IC 2 for
UART2). To enable this mode, you must program the
input capture module to detect the falling and rising
edges of the Start bit.
15.10 UART Operation During CPU
Sleep and Idle Modes
15.10.1 UART OPERATION DURING CPU
SLEEP MODE
When the device enters Sleep mode, all clock sources
to the module are shut down and stay at logic ‘0’. If
entry in to Slee p mod e occ urs whi le a tr ansmi ssio n is i n
progress, then the transmission is aborted. The UxTX
pin is driven to logic ‘1’. Similarly, if entry into Sleep
mode occurs while a reception is in progress, then the
reception is aborted. The UxSTA, UxMODE, transmit
and receive registers and buffers, and the UxBRG
register are not affected by Sleep mode.
If the W AKE bit (UxMODE <7>) is set before the device
enters Sleep mode, t hen a falling edg e on the UxRX pin
will gen era te a rec eive interrupt. The Recei ve Interru pt
Select mode bit (URXISEL) has no effect for this func-
tion. If the receive interrupt is enabled, then this will
wake-u p the dev ic e from Sl eep . Th e UA RTEN bit m us t
be set in order to generate a wake-up interrupt.
15.10.2 UART OPERATION DURING CPU
IDLE MODE
For the UART, the USIDL bit selects if the module will
stop operation when the device enters Idle mode or
whethe r the m odu le wi ll co nti nue on Idl e. If U SID L = 0,
the module will continue operation during Idle mode. If
USIDL = 1, the module will stop on Idle.

16.0 12-BIT ANALOG-TO-DIGITAL
CONVERTER (ADC) MODULE
The 12-bit Analog-to-Digital Converter allows conver-
sion of an analo g input s ignal to a 12-bit di gital number.
This module is based on a Successive Approximation
Register (SAR) architecture and provides a maximum
sampling rate of 200 ksps. The ADC module has up to
10 analog inputs which are multiplexed into a sample
and hold amplifier. The output of the sample and hold
is the input into the converter which generates the
result. Th e analog refe rence volt age is s oftware selec t-
able to either the device supply voltage (A VDD/AVSS) or
the voltage level on the (VREF+/VREF-) pin. The ADC
has a unique feature of being able to operate w hi le th e
device is in Sleep mode with RC oscillator selection.
The ADC module has six 16-bit registers:
A/D Control Register 1 (ADCON1)
A/D Control Register 2 (ADCON2)
A/D Control Register 3 (ADCON3)
A/D Input Select Register (ADCHS)
A/D Port Configuration Register (ADPCFG)
A/D Input Scan Selection Register (ADCSSL)
The ADCON1, ADCON2 and ADCON3 registers
control the operation of the ADC module. The ADCHS
register selects the input channels to be converted. The
ADPCFG register configures the port pins as analog
inputs or as digital I/O. The ADCSSL register selects
input s for sca nni ng .
The block diagram of the 12-bit ADC module is shown
in Figure 16-1.

not be written to while ADON = 1. This

16.1 A/D Result Buffer
The module contains a 16-word dual port read-only
buffer, called ADCBUF0...ADCBUFF, to buffer the A/D
results. The RAM is 12 bits wide but the data obtained
is represented in one of four different 16-bit data for-
mats. The contents of the sixteen A/D Conversion
Result Buffer registers, ADCBUF0 through ADCBUFF,
cannot be written by user software.
16.2 Conversion Operation
After the ADC mo dule has been configured, the sample
acquisition is started by setting the SAMP bit. Various
sources, such as a programmable bit, timer time-outs
and extern al event s, will ter minate acq uisition and st art
a conversion. When the A/D conversion is complete,
the result is loaded into ADCBUF0...ADCBUFF, and
the DONE bit and the A/D interrupt flag, ADIF, are set
after the number of samples specified by the SMPI bit.
The ADC module can be configured for different inter-
rupt rates as describ ed in Section 16.3 “Selecti ng the
Conversion Sequence”.
The following steps should be followed for doing an
A/D conversion:
1. Configure the ADC module:
Configure analog pins, voltage reference and
digital I/O
Select A/D input channels
Select A/D conver si on cl ock
Select A/D conversi on trigger
Turn on ADC module
2. Configure A/D interrupt (if required):
Clear ADIF bit
Select A/D interrupt priority
3. Start sampling
4. Wait the required acquisition time
5. Trigger acquisition end, start conversion
6. Wait for A/D conversion to complete, by either:
Waiting for the A/D interrupt, or
Waiting for the DONE bit to get set
7. Read A/D result buffer; clear ADIF if required
16.3 Selecting the Convers ion
Sequence
Several groups of control bits select the sequence in
which the A/D connects inputs to the sample/hold
channel, converts a channel, writes the buffer memory
and generates interrupts.
The sequence is controlled by the sampling clocks.
The SMPI bits select the number of acquisition/
convers io n s eq uen ce s that woul d b e p erfo rmed before
an interrupt occurs. This can vary from 1 sample per
interrupt to 16 samples per interrupt.
The BUFM bit will split the 16-word results buffer into
two 8-word groups. Writing to the 8-word buffers will be
alternated on each interrupt event.
Use of the BUFM bit will depend on how much time is
available for the moving of the buffers after the
interrupt.
If the processor can quickly unload a full buffer within
the time it takes to acquire and convert one channel,
the B UFM bit can be 0 a nd up to 16 conv ersio ns (c or-
responding to the 16 input channels) may be done per
interrupt. The processor will have one acquisition and
conversion time to move the sixteen conversions.
If the processor cannot unload the buffer within the
acquisition and conversion time, the BUFM bit should be
1’. For example, if SMPI<3:0> (ADCON2<5:2>) = 0111,
then eight conversions will be loaded into 1/2 of the
buffer, following which an interrupt occurs. The next
eight conversions w ill b e load ed into the o ther 1/2 o f the
buffer. The processor will have the entire time between
interrupts to move the eig ht convers ions.
The ALTS bit can be used to alternate the inputs
selected during the sampling sequence. The input
multiplexer has two sets of sample inputs: MUX A and
MUX B. If the ALTS bit i s ‘0’, onl y the MUX A input s are
selected for sampling. If the ALTS bit is ‘1’ and
SMPI<3:0> = 0000 on the first sample/convert
sequence, the MUX A inputs are selected and on the
next acquire/convert sequence, the MUX B inputs are
selected.
The CSCNA bit (ADCON2<10>) will allow the multi-
plexer input to be alternately scanned across a
select ed number of analog i nputs for the MUX A g roup.
The inputs are selected by the ADCSSL register. If a
particular bit in the ADCSSL register is ‘1’, the corre-
sponding input is selected. The inputs are always
scanne d from low er to higher numbered in puts, st arting
after each interrupt. If the number of inputs selected is
greate r than the number of s amples ta ken per int errupt,
the higher numbered inputs are unused.

dsPIC30F2011/2012/3012/3013
16.4 Programming the Start of
Conversion Trigger
The conversion trigger will terminate acquisition and
start the requested conversions.
The SSRC<2:0> bits select the source of the conver-
sion tri gger . The SSRC bi ts provide fo r up to 4 alterna te
sources of conversion trigger.
When SSRC<2:0> = 000, the conversion trigger is
under software control. Clearing the SAMP bit will
cause the co nve r si on trigger.
When SSRC<2:0> = 111 (Auto-Start mode), the con-
version trigger is under A/D clock control. The SAMC
bits select the number of A/D clocks between the start
of acquis ition and the st art of conversi on. This provide s
the fastest conversion rates on multiple channels.
SAMC must always be at least 1 clock cycle.
Other trigger sources can come from timer modules or
external interrupts.
16.5 Aborting a Conversion
Clearing the ADON bit during a conversion will abort
the cu rrent conv ersion a nd stop the sam pling s equenc-
ing until the next sampling trigger . The ADCBUF will not
be updated with the partially completed A/D conversion
sample. That is, the ADCBUF will continue to contain
the value of the last completed conversion (or the last
value written to the ADCBUF register).
If the clearing of the ADON bit coincides with an auto-
start, the clearing has a higher priority and a new
conversion will not start.
After the A/D conversion is aborted, a 2 TAD wait is
required before the next sampling may be started by
setting the SAMP bit.
16.6 Selecting the ADC Conversion
Clock
The ADC conversion requires 14 TAD. The source of
the AD C conv ersio n clo ck is softw are s elect ed, u sing a
six-bit counter. There are 64 possible options for TAD.
EQUATION 16-1: ADC CONVERSION
CLOCK
The internal RC oscillator is selected by setting the
ADRC bit.
For correct ADC conversions, the ADC conversion
clock (TAD) must be se lec t ed to en su re a minimu m TAD
time of 33 4 nsec (for VDD = 5V). Refe r to Section 20.0
“Electrical Characteristics” for minimum TAD under
other ope rati ng con di tion s.
Example 16-1 shows a sample calculation for the
ADCS<5:0> bits, assuming a device operating speed
of 30 MIPS.
EXAMPLE 16-1: ADC CONVE RSION

TAD = T CY * (0.5*(ADCS<5:0> + 1))

= 15 x 334 nsec
Therefore,

The configuration procedures below give the required
setup values for the conversion speeds above 100
ksps.
16.7.1 200 KSPS CONFIGURATION
GUIDELINE
The following configuration items are required to
achieve a 200 ksps conversion rate.
Compl y with con di t ion s provided in Table 16-1.
Connect external VREF+ and VREF- pins following
the recommended circuit shown in Figure 16-2.
Set SSRC<2.0> = 111 in the ADCO N1 regist er to
enable the auto convert option .
Enable automatic sampling by setting the ASAM
control bit in the ADCON1 register.
Write the SMPI<3 .0> con trol bit s in the ADCON2
register for the desired number of conversions
between interrupts.
Configure the A DC c l ock period to be:
by writing to the ADCS<5:0> control bits in the
ADCON3 register.
Configure the sampling time to be 1 TAD by
writing: SAMC<4:0> = 00001.
The following figure shows the timing diagram of the
ADC running at 200 ksps. The T AD selection in conjunc-
tion with the guidelines described above allows a con-
version speed of 200 ksp s. See Ex ample 16-1 for cod e
example.
16.8 A/D Acquisition Requirements
The analog input model of the 12-bit ADC is shown in
Figure 16-3. The total sampling time for the A/D is a
function of the internal amplifier settling time and the
holding capacitor charge time.
For the ADC to meet its specified accuracy, the charge
holding capacitor (CHOLD) must be allowed to fully
charge to the vo lta ge level on the an alog input pin . The
source impedance (RS), the interconnect impedance
(RIC), and the internal sampling switch (RSS) imped-
ance combine to directly affect the time required to
charge the capacitor CHOLD. The combined imped-
ance of the analog sources must therefore be small
enoug h to ful ly ch arg e th e hol ding c apac itor wit hin t he
chosen sample time. To minimize the effects of pin
leakage currents on the accura cy of the ADC, the max -
imum rec om me nde d so urc e im pe dan ce , RS, is 2. 5 kΩ.
After the analog input channel is selected (changed),
this s ampli ng fun ction must be com pleted prior to st a rt-
ing the conversion. The internal holding capacitor will
be in a discharged state prior to each sample opera-
tion.

16.9 Module Power-Down Modes
The module has 2 internal power modes.
When the ADON bit is ‘1’, the module is in Active mode;
it is fully powered and functional.
When AD ON is 0’, the modul e is in Of f mo de. The dig-
ital and analog portions of the circuit are disabled for
maximum curr ent savings.
In order to return to the Acti ve mode from O ff mode, th e
user must wait for the ADC circuitry to stabilize.
16.10 A/D Operation During CPU Sleep
and Idle Modes
16.10.1 A/D OPERATION DURING CPU
SLEEP MODE
When the de vice ente rs Sleep mod e, all cl ock sources
to the module are shut down and stay at logic ‘0’.
If Sleep occurs in the middle of a conversion, the con-
version is aborted. The converte r will not c onti nue with
a partially completed conversion on exit from Sleep
mode.
Register contents are not affected by the device
entering or leaving Sleep mode.
The ADC module can operate during Sleep mode if the
A/D clock source is set to RC (ADRC = 1). When the RC
clock source is selected, the ADC module waits one
instruction cycle before starting the conversion. This
allows the SLEEP instru ction t o be ex ecuted which elim-
inates all digital switching noise from the conversion.
When the conversion is complete, the CO NV bit will b e
cleared and the result loaded into the ADCBUF register.
If the A/D interrupt is enabled, the device will wake-up
from Sleep. If the A/D interrupt is not enable d, the ADC
module will then be turned off, although the ADON bit
will remain set.
16.10.2 A/D OPERATION DURING CPU IDLE
MODE
The ADSIDL bit select s if the mod ule will stop on Idle or
continue on Idle. If ADSIDL = 0, the module will con-
tinue operation on assertion of Idle mode. If ADSIDL =
1, the module will stop on Idle.
16.11 Effects of a Reset
A device Reset forces all registers to their Reset state.
This forces the ADC module to be turned off, and any
conversion and sampling sequence is aborted. The val-
ues that ar e in th e ADCBUF reg isters are not m odifie d.
The A/D Res ult registe r will cont ain unkno wn dat a after
a Power-on Rese t.
16.12 Output Formats
The A/D result is 12 bits wide. The data buffer RAM is
also 12 b it s wid e. The 12 -bit data can be rea d in one of
four different formats. The FORM<1:0> bits select the
format. Each of the outpu t format s trans lates t o a 16-bit
result on the data bus.

dsPIC30F2011/2012/3012/3013
16.13 Configuring Analog Port Pins
The use of the ADPC FG and TRIS registers control the
operation of the A/D port pins. The port pins that are
desired as analog inputs must have their correspond-
ing TRIS bit set (input). If the TRIS bit is cleared (out-
put), the digital output level (VOH or VOL) will be
converted.
The A/D operation is independent of the state of the
CH0SA<3:0>/CH0SB<3:0> bits and the TRIS bits.
When reading the POR T regist er , all pins c onfigured as
analog input channels will read as cleare d.
Pins configured as digital inp uts will not convert an ana-
log input. Analog levels on any pin that is defined as a
digital input (including the ANx pins) may cause the
input buffer to consume current that exceeds the
device specifications.
16.14 Connection Considerations
The anal og inp uts h ave diod es to VDD and V SS as ESD
protection. This requires that the analog input be
betwee n VDD and VSS. If the input voltage exceeds this
range by greater th an 0.3V (eit her direct ion), one o f the
diodes becomes forward b iased and it may damage the
device if the input curre nt specificati on is exce ede d.
An external RC filter is sometimes added for anti-
aliasi ng of the input signal. The R component should be
select ed to ens ure that th e sampl ing time requirem ents
are satisfied. Any external components connected (via
high-impedance) to an analog input pin (capacitor,
zener diode, etc.) should have very little leakage
current at the pin.

17.0 SYSTEM INTEGRATION
There are several features intended to maximize sys-
tem reliability, minimize cost through elimination of
external compone nts, pro vide Power Sav ing Oper ating
modes and of fer code protection:
Oscillator Selection
Reset
- Power-on Reset (POR)
- Power-up Timer (PWRT)
- Oscillator Start-up Timer (OST)
- Programmable Brown-out Reset (BOR)
Watchdog Timer (WDT)
Low-Voltage Detect
Power-Saving Modes (Sleep and Idle)
Code Protection
Unit ID Locations
In-Circuit Serial Programming (ICSP)
dsPIC30F devices have a Watchdog Timer which is
permanently enabled via the Configuration bits or can
be software controlled. It runs off its own RC oscillator
for added reliability. There are two timers that offer
necessary delays on power-up. One is the Oscillator
Start-up Timer (OST), intended to keep the chip in
Reset until the crystal oscillator is stable. The other is
the Power-u p Timer (PWR T) which prov ides a delay on
power-u p only, designed to keep the part in R eset while
the power supply stabilizes. With these two timers
on-chip, most applications need no external Reset
circuitry.
Sleep mode is designed to offer a very low current
Power-Down mode. The user ca n wake -up fro m Slee p
through external Reset, Watchdog Timer Wake-up, or
through an inte rrupt. Several os cillator opti ons are also
made available to allow the part to fit a wide variety of
applications. In the Idle mode, the clock sources are
still active but the CPU is shut-off. The RC oscillator
option saves system cost while the LP crystal option
saves power.
17.1 Oscillator System Overview
The dsPIC30F oscillator system has the following
modules and features:
Various external and internal oscillator options as
clock sources
An on-chip PLL to boost internal operating
frequency

17.2 Oscillator Configurations
17.2.1 INITIAL CLOCK SOURCE
SELECTION
While coming out of Power-on Reset or Brown-out
Reset, th e device sel ects its clock source based on:
a) FOS<2:0> Configuration bits that select one of
four oscillator groups,
b) and FP R<4:0> Configu ration bit s that select one
of 15 o scillat or choic es within the prim ary grou p.
The selection is as shown in Table 17-2.
17.2.2 OSCILLATOR START-UP TIMER
(OST)
In order to ensure that a crystal oscillator (or ceramic
resonator) has started and stabilized, an Oscillator
Start-up Timer is included. It is a simple 10-bit counter
that counts 1024 TOSC cycles before releasing the
oscillator clock to the rest of the system. The time-out
period is designated as TOST.
The TOST time is involved every time the oscillator has
to rest art (i.e ., on POR, BO R and wake-u p from Sleep ).
The Osc il lat or Start-up Time r is app lie d to the LP osci l-
lator, XT, XTL and HS modes (upon wake-up from
Sleep, POR and BOR) for the primary oscillator.

17.2.3 LP OSCILLATOR CONTROL
Enabli ng the LP oscillator is controlled with two elements:
1. The current oscillator group bits COSC<2:0>.
2. The LPOSCEN bit (OSC CO N regis ter).
The LP oscillator is on (even during Sleep mode) if
LPOSCEN = 1. The LP oscillator is the device clock if:
COSC<2: 0> = 000 (LP selected as main oscillator )
and
LPOSCEN = 1
Keeping t he LP oscillator on at all times allows for a fast
switch to the 32 kHz system clock for lower power oper-
ation. Returning to the faster main oscillator will still
require a start-up time
17.2.4 PHASE LOCKED LOOP (PLL)
The PLL multi plies the clock wh ic h is gen era ted by the
primary oscillator or Fast RC oscillator. The PLL is
select able t o have either ga ins of x 4, x8, and x16. Inp ut
and output frequency ranges are summarized in
Table 17-3.
TABLE 17-3: PLL FREQUENCY RANGE
The PLL fea tures a lo ck out put which is assert ed whe n
the PLL enters a phase locked state. Should the loop
fall out of lock (e.g ., due to nois e), the lock signal will b e
rescinded. The state of this signal is reflected in the
read-only LOCK bit in the OSCCON register.
17.2.5 FAST RC OSCILLATOR (FRC)
The FRC oscillator is a fast (7.37 MHz ±2% nominal)
inter nal RC o scil lat or. This osci llator is inten ded to p ro-
vide reasonable device operating speeds without the
use of an external crystal, ceramic resonator, or RC
network. The FRC oscillator can be used with the PLL
to obtain higher clock frequencies.
The dsPIC3 0F o pera t es fro m th e F RC o sc illator when-
ever the current oscillator selection control bits in the
OSCCO N register (OSC CON<14:12 >) are set to ‘001’.
The four bit field specified by TUN<3:0> (OSCTUN
<3:0>) allows the user to tune the internal fast RC
oscillator (nominal 7.37 MHz). The user can tune the
FRC oscillator within a range of +10.5% (840 kHz)
and -12% (960 kHz) in steps of 1.50% around the
factory-calibrated setting, see Table 17-4.
If OSC CON<14:12> are set to 111’ and F PR<4:0> a re
set to ‘00001’, ‘01010’ or ‘00011’, then a PLL
multiplier of 4, 8 or 16 (respectively) is applied.
TABLE 17-4: FRC TUNING
17.2.6 LOW-POW ER RC OSCILLATOR
(LPRC)
The LPRC oscillator is a component of the Watchdog
Timer (WDT) and oscillates at a nominal frequency of
512 kHz. The LPRC oscillator is the clock source for
the Power-up Timer (PWRT) circuit, WDT and clock
monitor circuits. It may also be used to provide a low-
frequency clock source option for applications where
power consumption is critical and timing accuracy is
not required.
The LPRC oscillator is always enabled at a Power-on
Reset because it is the clock source for the PWRT.
After the PWRT expires, the LPRC oscillator will
remain on if one of the following is true:
The Fail-Safe Clock Monitor is enabled
The WDT is enabled
The LPRC oscillator is selected as the system
clock via the COSC<2:0> control bits in the
OSCCON register
If one of the above conditions is not true, the LPRC will
shut-off after the PWRT expires.

17.2.7 FAIL-SAFE CLOCK MONITOR
The Fail-Saf e Cl oc k Mo nit or (F SCM) al low s the dev ic e
to conti nue to operate even i n the e vent o f an os cilla tor
failure. The FSCM functi on i s e nab le d by ap pro pria tel y
programming the FCKSM Configuration bits (clock
switch and monito r sele cti on bits ) in the FOSC Devi ce
Config uration regi ster. If the FSCM fu nction is enabled,
the LPRC i ntern al osc illator will run at al l tim es (ex ce pt
during Sl eep mode) an d will not be sub ject to contro l by
the SWDTEN bit.
In the event of an oscillator failure, the FSCM will gen-
erate a clock failure trap event and will switch the sys-
tem cloc k ove r to the FRC oscil lator. The us er w ill the n
have the op tion to either att empt to restart the oscil lator
or exec ute a controlled shutdown . The user may decide
to treat th e tra p a s a warm Res et by si mp ly loading the
Reset address into the oscillator fail trap vector. In this
event, the CF (Clock Fail) bit (OSCCON<3>) is also s et
whenever a clock failure is recognized.
In the event of a clock failure, the WDT is unaffected
and continues to run on the LPRC clock.
If th e oscillator h as a very slow st art-up time coming out
of POR, BOR or Sleep, it is possible that the PWRT
timer will expire before the oscillator has started. In
such ca se s, the FSCM wil l be act ivated and the FSCM
will i nitiate a c lock failu re trap, and the COSC<2 :0> bit s
are lo aded with FRC os cillator sele ction. This wil l effe c-
tively shut-off the original oscillator that was trying to
start.
The user may detect this situation and restart the
oscillator in the clock fail trap ISR.
Upon a clock failure detection, the FSCM module will
initiate a clock switch to the FRC oscillator as follows:
1. The COSC bits (OSCCON<14:12>) are loaded
with the FRC oscillator selection value.
2. CF bit is set (OSCCON<3>).
3. OSWEN control bit (OSCCON<0>) is cleared.
For the purpose of clock switching, the clock sources
are sectioned into four groups:
1. Primary (with or without PLL)
2. Secondary
3. Internal FRC
4. Internal LPRC
The user can switch between these functional groups
but canno t switch between opt ions within a group. If the
primary group is selected, then the choice within the
group is always determined by the FPR<4:0> Configu-
ration bits.
The OSCCON register holds the Control and Status
bits related to clock switching.
COSC<2:0>: Read-only bits always reflect the
current oscillator group in effect.
NOSC<2:0>: Control bits which are written to
indicate the new oscillator group of choice.
- On POR and BOR, COSC<2:0> and
NOSC <2:0> are both loaded with the Config-
uration bit values FOS<2:0>.
LOCK: The LOCK bit indicates a PLL lock.
CF: Read-only bit indicating if a clock fail detect
has occurred.
OSWEN: Control bit changes from a ‘0’ to a ‘1
when a clock transition sequence is initiated.
Clearing the OSWEN control bit will abort a clock
transition in progress (used for hang-up
situations).
If Configuration bits FCKSM<1:0> = 1x, then the clock
switching and Fail-Safe Clock monitoring functions are
disabled. This is the default Configuration bit setting.
If clock switching is disabled, then the FOS<2:0> and
FPR<4:0> bits directly control the oscillator selection
and the C OSC<2:0> b its do not contro l the clock selec-
tion. However, these bits will reflect the clock source
selection.
17.2.8 PROTECTION AGAINST
ACCIDENTAL WRITES TO OSCCON
A write to the OSCCON regis ter is intentionally made
difficult because it controls clock switching and clock
scaling.
To write to the OSCCON low byte, the following code
sequence must be executed without any other
instructions in between:
Byte wri te is allo wed for one i nstruction cycle. W rite the
desired value or use bit manipulation instruction.
To write to the OSCCON high byte, the following
instructions must be executed without any other
instructions in between:
Byte wri te is allo wed for one i nstruction cycle. W rite the
desired value or use bit manipulation instruction.
Note: The application should not attempt to
switch to a clock of frequency lower than
100 kHz when the Fail-Safe Clock Monitor
is enabled. If such clock switching is
performed, the device may generate an
oscillator fail trap and switch to the Fast RC
oscillator.

17.3 Reset
The PIC18F1220/1320 differentiates between various
kinds of Re set :
a) Power-on Reset (POR)
b) MCLR Reset during normal operation
c) MCLR Reset during Sleep
d) Watchdog Timer (WDT) Reset (during normal
operation)
e) Programmable Brown-out Reset (BOR)
f) RESET Inst ruction
g) Reset caused by trap lockup (TRAPR)
h) Reset caused by illegal opcode or by using an
uninitialized W register as an address pointer
(IOPUWR)
Dif fer ent regi sters a re a ffe cted in dif fe rent w ays by var-
ious Reset conditions. Most registers are not affected
by a WD T wake-u p since th is is view ed as the resum p-
tion of normal operation. Status bits from the RCON
register are set or cleared differently in different Reset
situations, as indicated in Table 17-5. These bits are
used in s oftwa re to dete rmi ne th e na ture of the Reset.
A block d iag ram of the On -C hi p Res et C ircui t is sho w n
in Figure 17-2.
A MCLR noise filter is provided in the MCLR Reset
path. The filter detects and ignores small pulses.
Internall y generated Res ets do not drive MCLR pi n low .
FIGURE 17-2: RESET SYSTEM BLOCK DIAGRAM
17.3.1 PO R: POW ER- ON RESE T
A power-on event will generate an internal POR pulse
when a VDD rise is detected. The Reset puls e will occur
at the POR circuit threshold voltage (VPOR) which is
nominally 1.85V. The device supply voltage character-
istics mus t meet spec ified sta rting v olt ag e and rise ra te
requirements. The POR pulse will reset a POR timer
and place the device in the Reset state. The POR also
selects the device clock source identified by the
oscillator configuration fuses.
The POR circuit inserts a small delay, TPOR, which is
nominally 10 μs and ensures that the device bias cir-
cuits are stable. Furthermore, a user selected power-
up time-out (TPWRT) is applied. The TPWRT pa ra me te r
is based on device Configuration bits and can be 0 ms
(no delay), 4 ms, 16 ms or 64 ms. The total delay is at
device power-up, TPOR + TPWRT. When these delays
have expired, SYSRST will be negated on the next
leading edge of the Q1 clock a nd the PC will j ump to the
Reset vector.
The timing for the SYSRST signal is shown in
Figure 17-3 through Figure 17-5.

17.3.1.1 POR with Long Crystal Start-up Time
(with FSCM Enabled)
The osci ll ator s t art-up circuit r y is not linked to the POR
circuitry. Some crystal circuits (especially low fre-
quency crystals) will have a relatively long start-up
time. Th erefore, one or more of the foll owing condit ions
is possible after the POR timer and the PWRT have
expired:
The oscillator circuit has not begun to oscillate.
The Osc ill ato r Start-up Timer ha s not expi red (if a
crystal oscillator is used).
The PLL has not achieved a L OCK (if PLL is
used).
If th e FSCM is enabled and one of th e above c onditions
is true, then a clock failure trap will occur. The device
will automatically switch to the FRC oscillator and the
user can switch to the desired crystal oscillator in the
trap ISR.
17.3.1.2 Operating without FSCM and PWRT
If the FSCM is disabled and the Power-up Timer
(PWRT) is also disabled, then the device will exit rap-
idly from Reset on power-up. If the clock source is
FRC, LPRC, ERC or EC, it will be active immediately.
If the FSCM is disabled and the system clock has not
start ed, the de vice w ill be in a frozen st ate at th e Res et
vector until the system clock starts. From the user’s
perspective, the device will appear to be in Reset until
a system clock is available.
17.3.2 BO R: PRO GR A MMABLE
BROWN-OUT RESET
The BOR (Brown-out Reset) module is based on an
internal voltage reference circuit. The main purpose of
the BOR mod ul e is to ge nera t e a d evic e R eset w he n a
brown-out condition occurs. Brown-out conditions are
generally caused by glitches on the AC mains (i.e.,
missing portions of the AC cycle waveform due to bad
power tr ansmission lines, or voltage sags due to exces-
sive current draw when a larg e in duc tiv e l oad is turne d
on).
The BOR module allows selection of one of the
following voltage trip points (see Table 20-11):
2.6V-2.71V
•4.1V-4.4V
4.58V-4.73V
A BOR will generate a Reset pul se which will rese t the
device. The BOR will select the clock source based on
the device Configuration bit values (FOS<2:0> and
FPR<4:0>). Furthermore, if an Oscillator mode is
selected, the BOR will activate the Oscillator Start-up
Timer (OST). The system clock is held until OST
expires. If the PLL is used, then the clock will be held
until the LOCK bit (OSCCON<5>) is ‘1’.
Concurrently, the POR time-out (TPOR) and the PWRT
time-out (TPWRT) will be applied before the internal Reset
is rele as ed . If TPWRT = 0 and a crystal oscillato r is being
used, then a nominal delay of TFSCM = 100 μs is applied.
The total delay in this case is (TPOR + TFSCM).
The BOR Status bit (RCON<1>) will be set to indicate
that a BOR has occurred. The BOR circuit, if enabled,
will continue to operate while in Sleep or Idle modes
and wi ll reset the de vice shoul d VDD fall below the BOR
threshold voltage.
FIGURE 17-6: EXTERNAL POWER-ON
RESET CIRCUIT (FOR
SLOW VDD POWER-UP)
Note: The BOR voltage trip points indicated here
are nominal values provided for design
guidance only. Refer to the Electrical
Specifications in the specific device data
sheet for BOR voltage limit specifications.
Note: Dedicated supervisory devices, such as
the MCP1XX and MCP8XX, may also be
used as an external Power-on Reset
circuit.
Note 1: Ext ernal Power- on Reset circuit is required
only if the VDD power-up slope is too slow.
The diode D helps discharge the capacitor
quickly when VDD powers down.
2: R should be suitably chosen so as to make
sure that the voltage drop across R does not
violate the device’s electrical specifications.
3: R1 should be suitably chosen so as to limit
any current flowing into MCLR from exte r n al
capacitor C, in the event of MCLR/VPP pin
breakdown due to Electrostatic Discharge
(ESD) or Electrical Overstress (EOS).

17.4 Watchdog Ti mer (WDT)
17.4.1 W ATCHDOG TIMER OPERATION
The primary function of the Watchdog Timer (WDT) is
to reset the processor in the event of a software mal-
function. The WDT is a free-running timer which runs
off an on-chip RC oscil lator, requi ring no e xte rnal com -
ponent. Th erefore, the WDT tim er will continue to oper-
ate even if the main processor clock (e.g., the crystal
oscillator) fails.
17.4.2 ENABLING AND DISABLING
THE WDT
The Watchdog Timer can be “Enabled” or “Disabled”
only through a Configuration bit (FWDTEN) in the
Configu ration register, FWDT.
Setting FWDTEN = 1 enables the W atchdog T imer . The
enabling is done when programming the device. By
default, af ter chip erase, FWDTEN bit = 1. A ny device
programmer capable of programming dsPIC30F
devices a llows pro gr amming of t his a nd oth er C onfi gu-
rat i on bi ts.
If enabled, the WDT will increment until it overflows or
“times out”. A WDT time-out will force a device Reset
(except during Sleep). To prevent a WDT time-out, the
user must clear the Watchdog Timer using a CLRWDT
instruction.
If a WDT times out during Sleep, the device will wake-
up. The WDT O bit in the RCO N register wil l be cleare d
to indicate a wake-up resulting from a WDT time-out.
Setting FWDTEN = 0 allows user software to enable/
disable the Watchdog Timer via the SWDTEN
(RCON<5>) control bit.
17.5 Low Volt age Detect
The Low V oltage Detect (LVD) mod ule is used to detect
when the VDD of the device drops below a threshold
value, VLVD, which is determined by the LVDL<3:0>
bits (RCON<11:8>) and is thus user programmable.
The intern al volt age referenc e circuitry requires a nom-
inal amount of time to stabilize, and the BGST bit
(RCON<13 >) indicates w hen the volt age reference ha s
stabilized.
In some devices, the LVD threshold voltage may be
applied extern al ly on the LVDIN pin.
The LVD module is enabled by setting the LVDEN bit
(RCON<12>).
17.6 Power-Saving Modes
There are tw o power-s avin g state s that c an be en tered
through the execu tio n of a spe cial inst ruct ion, PWRSAV;
these are Sleep and Idle.
The format of the PWRSAV instruction is as follows:
PWRSAV <parameter>, where ‘parameter’ def ines
Idle or Sleep mode.
17.6.1 SL EE P MODE
In Sleep m ode, th e clo ck to the C PU and p eriphe rals i s
shut down. If an on-chip oscillator is being used, it is
shut down .
The Fail-Safe Clock Monitor is not functional during
Sleep since there is no clock to monitor. However,
LPRC clock remains active if WDT is operational during
Sleep.
The brown-out protection circuit and the Low-Voltage
Detect circuit, if enabled, will remain func tional during
Sleep.
The processor wakes up from Sleep if at least one of
the following conditions has occurred:
any interrupt that is individually enabled and
meets the required priority level
any Reset (POR, BOR and MCLR)
WDT time-out
On waking up from Sleep mode, the processor will
resta rt the sam e clock tha t was active prior to en try into
Sleep mode. When clock switching is enabled, bits
COSC<2:0> will determine the oscillator source that
will be used on wake-up. If clock switch is disabled,
then there is only one system clock.
If the clock source is an oscillator, the clock to the
device will be held off until OST times out (indicating a
stable oscillator). If PLL is used, the system clock is
held off until LOCK = 1 (indicating that the PLL is
stab le). I n eit her c ase, TPOR, T LOCK and TPWRT delay s
are applied.
If EC, FRC, LPRC or ERC oscillators are used, then a
delay of TPOR (~ 10 μs) is applied. This is the smallest
delay possible on wake-up from Sleep.
Moreover, if LP oscillator was active during Sleep and
LP is the oscillator used on wake-up, then the start-up
delay will be equal to TPOR. PWRT delay and OST
timer delay are not applied. In order to have the small-
est poss ible sta rt-up delay when waking up fro m Sleep,
one of these faste r wake-up optio ns shoul d be selecte d
before entering Sleep.
Note: If a POR or BOR occurred, the selection of
the oscillator is based on the FOS<2:0>
and FPR<4:0> Configuration bits.
dsPIC30F2011/2012/3012/3013
DS70139E-page 130 © 2006 Microchip Technology Inc.
Any interrupt that is individually enabled (using the cor-
responding IE bit) and meets the prevailing priority level
will be able to wake-up the processor . The processor will
process the interrupt and branch to the ISR. The Sleep
Status bit in the RCON register is s et upon w ake-up.
All Resets will wake-up the processor from Sleep
mode. Any Reset, other than POR, will set the Sleep
Status bit. In a POR, the Sleep bit is cleared.
If the Watchdog Timer is enabled, then the processor
will wake-up from Sleep mode u pon WDT time-out. Th e
Sleep and WDTO Status bits are both set.
17.6.2 IDLE MODE
In Idle mode, the clock to the CPU is shut down while
peripher als keep running. Unlike Sleep mode, the clock
sour ce rem ains active .
Several peripherals have a control bit in each module
that allows them to operate during Idle.
LPRC Fail-Safe Clock remains active if clock failure
detect is enabled.
The processor wakes up from Idle if at least one of the
following conditions has occurred:
any interrupt that is individually enabled (IE bit is
1’) and meets the r equired priority level
any Reset (POR, BOR, MCLR)
WDT time-out
Upon wake-up from Idle mode, the clock is re-applied
to the CPU and instruction execution begins immedi-
ately, st arting with the instructi on fol low i ng the PWRSAV
instruction.
Any interrupt that is individually enabled (using IE bit)
and meets the prevailing priority level will be able to
wake-up th e processor. The proce ss or wil l p roc es s th e
interrupt and branch to the ISR. The Idle Status bit in
the RCON register is set upon wake-up.
Any Reset other than POR will set the Idle Status bit.
On a POR, the Idle bit is cleared.
If Watchdog Timer is enabled, then the processor will
wake-up from Idle mode upon WDT time-out. The Idle
and WDTO Status bits are both set.
Unlike wake-up from Sleep, there are no time delays
involv ed in wa ke -up from Idle.
17.7 Device Configuration Registers
The Configuration bits in each device Configuration
register specify some of the device modes and are
prog ramme d by a de vice prog ra mmer, or by using the
In-Circuit Serial Programming™ (ICSP™) feature of
the device. Each device Configuration register is a
24-bit register, but only the lower 16 bits of each regis-
ter are used to hold configuration data. There are four
device Configuration registers available to the user:
1. FOSC (0xF80000): Oscillator Configuration
Register
2. FWDT (0xF80002): Watchdog Timer
Configu ration Register
3. FBORPOR (0xF80004): BOR and POR
Configu ration Register
4. FGS (0xF8000A): General Code Segment
Configu ration Register
The placement of the Configuration bits is automati-
cally ha ndled when you sel ect the device in your device
programmer . The desired state of the Configuration bit s
may be sp ecified i n the source code (depen dent on the
language tool used), or through the programming
interface. After the device has been programmed, the
application software may read the Configuration bit
values through the table read instructions. For addi-
tional information, please refer to the Programming
Specifications of the device.
Note: In spite of various delays applied (TPOR,
TLOCK and TPWRT), the crystal oscillator
(and PLL) may not be active at the end of
the time-out (e.g., for low-frequency crys-
tals). In such cases, if FSCM is enabled,
then the device will detect this as a clock
failure and process the clock failure trap, the
FRC oscillator will be enabled and the user
will have to re-enable the crystal oscillator . If
FSCM is not enabled, then the device will
simply su spend e xecuti on of code until the
cloc k i s stable an d w i ll rem a in in Sleep un ti l
the oscillator clock has started.
Note: If the code protection Configuration fuse
bits (FGS<GCP> and FGS<GWRP>)
have been programmed, an erase of the
entire code-protected device is only
possib le at vol tages VDD 4.5V.

dsPIC30F2011/2012/3012/3013
17.8 Peripheral Module Disable (PMD)
Registers
The Peripheral Module Disable (PMD) registers pro-
vide a method to disable a peripheral module by stop-
ping all clock so urc es sup pl ied to that modu le. When a
peripheral is disabled via the appropriate PMD control
bit, the peripheral is in a minimum power consumption
state. The C on trol an d St atus r egi ste r s as so ci ated w i th
the peripheral will also be disabled so writes to those
registers will have no effect and read values will be
invalid.
A peripheral module will only be enabled if both the
associated bit in the the PMD register is cleared and
the peripheral is supported by the specific dsPIC DSC
variant. If the peripheral is present in the device, it is
enabled in the PMD register by default.
17.9 In-Circuit Debugger
When M PLAB® ICD2 is selected as a De bugger , the In-
Circuit Debugging functionality is enabled. This func-
tion all ows simp le de buggin g func tions whe n used w ith
MPLAB IDE. When the device has this feature e nabled,
some of the resources are not available for general
use. These resources include the first 80 bytes of Data
RAM and two I/O pins.
One of four pairs of Debug I/O pins may be selected by
the user using configuration options in MPLAB IDE.
These pin pairs are named EMUD/EMUC, EMUD1/
EMUC1, EMUD2/EMUC2 and EMUD3/EMUC3.
In each c as e, th e se lec te d EMU D p in i s th e Em ula tio n/
Debu g Data li ne, and th e EMUC pi n is the E mulati on/
Debug Clock line. These pins will interface to the
MPLAB ICD 2 module available from Microchip. The
selected pair of Debug I/O pins is used by MPLAB
ICD 2 to send commands and receive responses, as
well as to send and receive data. To use the In-Circuit
Debugger function of the device, the design must
implement ICSP connections to MCLR, VDD, VSS,
PGC, PGD and the selected EMUDx/EMUCx pin pair.
This gives rise to two possibilities:
1. If EMUD/EMU C is selecte d as the Debug I/O pin
pair, then only a 5-pin interface is required, as
the EMUD and EMUC pin functions are multi-
plexed with the PGD and PGC pin functions in
all dsPIC30F devices.
2. If EMUD1/EMUC1, EMUD2/EMUC2 or EMUD3/
EMUC3 is selected as the Debug I/O pin pair,
then a 7-pin interface is required, as the
EMUDx/EMUCx pin functions (x = 1, 2 or 3) are
not multiplexed with the PGD and PGC pin
functions.
Note: If a PMD bit is set, the corresponding mod-
ule is d isabled after a delay of 1 instruc tion
cycle. Sim ilarly, if a PM D bit is clea red, th e
corresponding module is enabled after a
delay of 1 instruction cycle (assuming the
module Control registers are already
configured to enable module operation).
Note: In the dsPIC30F2011, dsPIC30F3012 and
dsPIC30F2012 devices, the U2MD bit is
readable and writable and will be read as
1’ when set.

18.0 INSTRUCTION SET SUMMARY
The dsPIC30F instruction set adds many
enhancements to the previous PIC® MCU instruction
sets , while mai ntaining an easy mi gration from PIC
MCU instruction sets.
Most instructions are a single program memory word
(24 bits). Only three instructions require two program
memory locations.
Each single-word instruction is a 24-bit word divided
into an 8-bit opcode which specifies the instruction
type, and one or more operands which further specify
the operation of the instruction.
The instruction set is highly orthogonal and is grouped
into five bas ic ca tego ries:
Word or byte-oriented operations
Bit-oriented operations
Literal operations
DSP operations
Control operations
Table 18-1 shows the general symbols used in
des c ribing t he instructions.
The dsPIC30F instruction set summary in Table 18-2
lists all the instructions, along with the status flags
affected by each instruction.
Most word or byte-oriented W register instructions
(including barrel shift instructions) have three
operands:
The first source operand which is typically a
register ‘Wb’ without any address modifier
The seco nd source operand which is typi cally a
register ‘Ws’ with or without an address modifier
The destination of the result which is typically a
register ‘Wd’ with or without an address modifier
However , word or byte-ori ented file register instructions
have two operands:
The file register specified by the value ‘f
The destination, which could either be the file
register ‘f’ or the W0 reg ister, which is de noted as
‘WREG’
Most bit-oriented instructions (including simple rotate/
shift instructions) have two operands:
The W register (with or without an address
modifier) or file register (specified by the value of
‘Ws’ or ‘f’)
The bit in the W register or file register
(specified by a literal value or indirectly by the
contents of register ‘Wb’)
The litera l instruct ions that invo lve data m ovement ma y
use some of the following operands:
A lite ral value to be lo aded i nto a W regi ster or file
register (specified by the value of ‘k’)
The W register or file register where the literal
value is to be loaded (specified by ‘Wb’ or ‘f’)
However, literal instructions that involve arithmetic or
logical operations use some of the following operands:
The first source operand which is a register ‘Wb’
without any addre s s modifier
The second source operand which is a literal
value
The dest ination of the result (only if not the same
as the first source operand) which is typically a
register ‘Wd’ with or without an address modifier
The MAC class of DSP instructions may use some of the
following operands:
The accumulator (A or B) to be used (required
operand)
The W regis ters t o be used as the two operands
The X and Y address space prefetch operations
The X and Y address space prefetch destinations
The accumulator writ e-ba ck destination
The other DSP instructions do not involve any
multipl ic ati on, and may include:
The accumul ator to be used (requ ired )
The source o r destin ation ope rand (des ignated as
Wso or Wdo, respectively) with or without an
address modifier
The amou nt of s hift sp ecifi ed by a W regis ter ‘Wn
or a literal value
The control instructions may use some of the following
operands:
A program memory address
The mode of the table read and table write
instructions

of dsPIC30F devices and is not intended to be a complete
reference source. For more information on the CPU,
peripherals, register descriptions and general device
functionality, refer to the “dsPIC30F Family Reference
Manual” (DS70046). For more information on the device

All instructions are a single word, except for certain
double-word instructions, which were made double-
word instructions so that all the required information is
available in these 48 bits. In the second word, the
8MSbs are0’s. I f thi s s e co nd wo r d i s e x ec ute d a s an
instruction (by itself), it will execute as a NOP.
Most single-word instructions are executed in a single
instruc tion cycle , u nle ss a co ndi tional test is tru e or the
program counter is changed as a result of the instruc-
tion. In these cases, the executio n takes tw o instructio n
cycles with the additional instruction cycle(s) executed
as a NOP. Notable exceptions are the BRA (uncondi-
tional/c ompu ted bra nch), i ndirec t CALL/GOTO, al l t abl e
reads and writes, and RETURN/RETFIE instructions,
which a re single -word in struction s but t ake two or thre e
cycles. Certain instructions that involve skipping over
the subsequent instruction require either two or three
cycles if the skip is performed, depending on whether
the instruction being skipped is a single-word or two-
word instruction. Moreover, double-word moves
require two cycles. The double-word instructions
execute in two instruction cycles.
Note: For more details on the instruction set,
refer to the Programmer’s Reference
Manual.

dsPIC30F2011/2012/3012/3013
DS70139E-page 142 © 2006 Microchip Technology Inc.
19.2 MPASM Assembler
The MPASM Assembler is a full-featured, universal
macro assemb ler for all PIC MCUs.
The MPASM Assembler generates relocatable object
files fo r the MPLINK Ob ject Linker , Int el® standa rd HEX
files, MAP files to detail memory usage and symbol
reference, absolute LST files that contain source lines
and generated machine code and COFF files for
debugging.
The MPASM Assembler features include:
Integration into MPLAB IDE projects
User-defined macros to streamline
assembly code
Conditional assembly for multi-purpose
sour ce fil es
Directives that allow complete control over the
assembly process
19.3 MPLAB C18 and MPLAB C30
C Compilers
The MPLAB C18 and MPLAB C30 Code Development
Systems are complete ANSI C compilers for
Microchip’s PIC18 family of microcontrollers and the
dsPIC30, dsPIC33 and PIC24 family of digital signal
controllers. These compilers provide powerful integra-
tion capabilities, superior code optimization and ease
of use not found with other compilers.
For easy source level debugging, the compilers provide
symbol info rmation tha t is optimized to the MPLAB IDE
debugger.
19.4 MPLINK Object Linker/
MPLIB Object Librari an
The MPLINK Object Linker combines relocatable
objects created by the MPASM Assembler and the
MPLAB C18 C Compiler. It can link relocatable objects
from precompiled libraries, using directives from a
linker script.
The MPLIB O bject Li brarian manag es the cre ation an d
modification of library files of precompiled code. When
a routine from a library is called from a source file , only
the modules that contain that routine will be linked in
with the application. This allows large libraries to be
used efficiently in many different applications.
The object linker/library features include:
Efficient linking of single libraries instead of many
smaller files
Enhanced code maintainability by grouping
related modules together
Flexible creation of libraries with easy module
listing, replacement, de letion and extraction
19.5 MPLAB ASM30 Assembler, Linker
and Librarian
MPLAB ASM30 Assembler produces relocatable
machine code from symbolic assembly language for
dsPIC30F devices. MPLAB C30 C Compiler uses the
assembler to produce its object file. The assembler
generates relocatable object files that can then be
archived or linke d with other relocatable ob ject files and
arch ives to c rea te an e xecu tabl e fil e. N otabl e fe atu res
of the assembler include:
Support for the entire dsPIC30F instruction set
Support for fixed-point and floating-point data
Command line interface
Rich dire cti ve set
Flexible macro language
MPLAB IDE compatibility
19.6 MPLAB SIM Software Simulator
The MPLAB SIM Software Simulator allows code
development in a PC-hosted environment by simulat-
ing the PIC MCUs and dsPIC® DSCs on an instruction
level. On any given instruction, the data areas can be
examined or modified and stimuli can be applied from
a comprehensive stimulus controller. Registers can be
logged to files for further run-time analysis. The trace
buffer and logic analyzer display extend the power of
the simulator to record and track program execution,
actions on I/O, most periph erals and inte rnal regi sters.
The MPLAB SIM Software Simulator fully supports
symbolic debugging using the MPLAB C18 and
MPLAB C30 C Compilers, and the MPASM and
MPLAB ASM30 Assemblers. The software simulator
offers the flexibility to develop and debug code outside
of the hardware laboratory environment, making it an
excellent, economical software development tool.
