It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to the dsPIC33F/PIC24H Family Reference Manual, which is available from the Microchip website (www.microchip.com). 2: Some registers and associated bits described in this section may not be available on all devices. Refer to Section 4.0 "Memory Organization" in this data sheet for device-specific register and bit information. 2.1 Basic Connection Requirements Getting started with the dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 family of 16-bit Digital Signal Controllers (DSC) requires attention to a minimal set of device pin connections before proceeding with development. The following is a list of pin names, which must always be connected: * All VDD and VSS pins (see Section 2.2 "Decoupling Capacitors") * All AVDD and AVSS pins (regardless if ADC module is not used) (see Section 2.2 "Decoupling Capacitors") * VCAP (see Section 2.3 "Capacitor on Internal Voltage Regulator (VCAP)") * MCLR pin (see Section 2.4 "Master Clear (MCLR) Pin") * PGECx/PGEDx pins used for In-Circuit Serial ProgrammingTM (ICSPTM) and debugging purposes (see Section 2.5 "ICSPTM Pins") * OSC1 and OSC2 pins when external oscillator source is used (see Section 2.6 "External Oscillator Pins") (c) 2008-2012 Microchip Technology Inc. 2.2 Decoupling Capacitors The use of decoupling capacitors on every pair of power supply pins, such as VDD, VSS, AVDD and AVSS is required. Consider the following criteria when using decoupling capacitors: * Value and type of capacitor: Recommendation of 0.1 F (100 nF), 10-20V. This capacitor should be a low-ESR and have resonance frequency in the range of 20 MHz and higher. It is recommended that ceramic capacitors be used. * Placement on the printed circuit board: The decoupling capacitors should be placed as close to the pins as possible. It is recommended to place the capacitors on the same side of the board as the device. If space is constricted, the capacitor can be placed on another layer on the PCB using a via; however, ensure that the trace length from the pin to the capacitor is within one-quarter inch (6 mm) in length. * Handling high frequency noise: If the board is experiencing high frequency noise, upward of tens of MHz, add a second ceramic-type capacitor in parallel to the above described decoupling capacitor. The value of the second capacitor can be in the range of 0.01 F to 0.001 F. Place this second capacitor next to the primary decoupling capacitor. In high-speed circuit designs, consider implementing a decade pair of capacitances as close to the power and ground pins as possible. For example, 0.1 F in parallel with 0.001 F. * Maximizing performance: On the board layout from the power supply circuit, run the power and return traces to the decoupling capacitors first, and then to the device pins. This ensures that the decoupling capacitors are first in the power chain. Equally important is to keep the trace length between the capacitor and the power pins to a minimum thereby reducing PCB track inductance. DS70318F-page 19 dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 FIGURE 2-1: RECOMMENDED MINIMUM CONNECTION 0.1 F Ceramic 10 F Tantalum R R1 VSS VDD 2.4 VCAP VDD dsPIC33F VSS VDD VSS VDD AVSS VDD AVDD VSS 0.1 F Ceramic 0.1 F Ceramic 0.1 F Ceramic L1(1) 1: As an option, instead of a hard-wired connection, an inductor (L1) can be substituted between VDD and AVDD to improve ADC noise rejection. The inductor impedance should be less than 1 and the inductor capacity greater than 10 mA.

C Note Master Clear (MCLR) Pin The MCLR functions: MCLR 0.1 F Ceramic The placement of this capacitor should be close to the VCAP. It is recommended that the trace length not exceed one-quarter inch (6 mm). Refer to Section 21.2 "On-Chip Voltage Regulator" for details. During device programming and debugging, the resistance and capacitance that can be added to the pin must be considered. Device programmers and debuggers drive the MCLR pin. Consequently, specific voltage levels (VIH and VIL) and fast signal transitions must not be adversely affected. Therefore, specific values of R and C will need to be adjusted based on the application and PCB requirements. For example, as shown in Figure 2-2, it is recommended that the capacitor C, be isolated from the MCLR pin during programming and debugging operations. Place the components shown in Figure 2-2 within one-quarter inch (6 mm) from the MCLR pin. FIGURE 2-2: EXAMPLE OF MCLR PIN CONNECTIONS VDD 2 R R1 MCLR 2.2.1 TANK CAPACITORS On boards with power traces running longer than six inches in length, it is suggested to use a tank capacitor for integrated circuits including DSCs to supply a local power source. The value of the tank capacitor should be determined based on the trace resistance that connects the power supply source to the device, and the maximum current drawn by the device in the application. In other words, select the tank capacitor so that it meets the acceptable voltage sag at the device. Typical values range from 4.7 F to 47 F. 2.3 Capacitor on Internal Voltage Regulator (VCAP) JP dsPIC33F C Note 1: R 10 k is recommended. A suggested starting value is 10 k. Ensure that the MCLR pin VIH and VIL specifications are met. 2: R1 470 will limit any current flowing into MCLR from the external capacitor C, in the event of MCLR pin breakdown, due to Electrostatic Discharge (ESD) or Electrical Overstress (EOS). Ensure that the MCLR pin VIH and VIL specifications are met. A low-ESR (< 5 Ohms) capacitor is required on the VCAP pin, which is used to stabilize the voltage regulator output voltage. The VCAP pin must not be connected to VDD, and must have a capacitor between 4.7 F and 10 F, 16V connected to ground. The type can be ceramic or tantalum. Refer to Section 24.0 "Electrical Characteristics" for additional information. DS70318F-page 20 (c) 2008-2012 Microchip Technology Inc. dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 2.5 ICSPTM Pins FIGURE 2-3: The PGECx and PGEDx pins are used for In-Circuit Serial ProgrammingTM (ICSPTM) and debugging purposes. It is recommended to keep the trace length between the ICSP connector and the ICSP pins on the device as short as possible. If the ICSP connector is expected to experience an ESD event, a series resistor is recommended, with the value in the range of a few tens of Ohms, not to exceed 100 Ohms. Pull-up resistors, series diodes, and capacitors on the PGECx and PGEDx pins are not recommended as they will interfere with the programmer/debugger communications to the device. If such discrete components are an application requirement, they should be removed from the circuit during programming and debugging. Alternatively, refer to the AC/DC characteristics and timing requirements information in the respective device Flash programming specification for information on capacitive loading limits and pin input voltage high (VIH) and input low (VIL) requirements. Ensure that the "Communication Channel Select" (i.e., PGECx/PGEDx pins) programmed into the device matches the physical connections for the ICSP to MPLAB(R) ICD 3 or MPLAB(R) REAL ICETM. For more information on ICD 3 and REAL ICE connection requirements, refer to the following documents that are available on the Microchip website. * "Using MPLAB(R) ICD 3" (poster) DS51765 * "MPLAB(R) ICD 3 Design Advisory" DS51764 * "MPLAB(R) REAL ICETM In-Circuit Debugger User's Guide" DS51616 * "Using MPLAB(R) REAL ICETM" (poster) DS51749 2.6 External Oscillator Pins SUGGESTED PLACEMENT OF THE OSCILLATOR CIRCUIT Main Oscillator 13 Guard Ring 14 15 Guard Trace Secondary Oscillator 16 17 18 19 20 2.7 Oscillator Value Conditions on Device Start-up If the PLL of the target device is enabled and configured for the device start-up oscillator, the maximum oscillator source frequency must be limited to 4 MHz < FIN < 8 MHz to comply with device PLL start-up conditions. This means that if the external oscillator frequency is outside this range, the application must start up in the FRC mode first. The default PLL settings after a POR with an oscillator frequency outside this range will violate the device operating speed. Once the device powers up, the application firmware can initialize the PLL SFRs, CLKDIV, and PLLDBF to a suitable value, and then perform a clock switch to the Oscillator + PLL clock source. Note that clock switching must be enabled in the device Configuration word. Many DSCs have options for at least two oscillators: a high-frequency primary oscillator and a low-frequency secondary oscillator (refer to Section 8.0 "Oscillator Configuration" for details). The oscillator circuit should be placed on the same side of the board as the device. Also, place the oscillator circuit close to the respective oscillator pins, not exceeding one-half inch (12 mm) distance between them. The load capacitors should be placed next to the oscillator itself, on the same side of the board. Use a grounded copper pour around the oscillator circuit to isolate them from surrounding circuits. The grounded copper pour should be routed directly to the MCU ground. Do not run any signal traces or power traces inside the ground pour. Also, if using a two-sided board, avoid any traces on the other side of the board where the crystal is placed. A suggested layout is shown in Figure 2-3. (c) 2008-2012 Microchip Technology Inc. DS70318F-page 21 dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 2.8 Configuration of Analog and Digital Pins During ICSP Operations If MPLAB ICD 2, ICD 3 or REAL ICE is selected as a debugger, it automatically initializes all of the A/D input pins (ANx) as "digital" pins, by setting all bits in the ADPCFG register. The bits in the registers that correspond to the A/D pins that are initialized by MPLAB ICD 2, ICD 3, or REAL ICE, must not be cleared by the user application firmware; otherwise, communication errors will result between the debugger and the device. If your application needs to use certain A/D pins as analog input pins during the debug session, the user application must clear the corresponding bits in the ADPCFG register during initialization of the ADC module. When MPLAB ICD 2, ICD 3, or REAL ICE is used as a programmer, the user application firmware must correctly configure the ADPCFG register. Automatic initialization of these registers is only done during debugger operation. Failure to correctly configure the register(s) will result in all A/D pins being recognized as analog input pins, resulting in the port value being read as a logic '0', which may affect user application functionality. 2.9 Unused I/Os Unused I/O pins should be configured as outputs and driven to a logic-low state. Alternatively, connect a 1k to 10k resistor between VSS and unused pins and drive the output to logic low. 2.10 Typical Application Connection Examples Examples of typical application connections are shown in Figure 2-4 through Figure 2-11.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 2. "CPU" (DS70204) in the "dsPIC33F/PIC24H Family Reference Manual", which is available from the Microchip web site (www.microchip.com). 2: Some registers and associated bits described in this section may not be available on all devices. Refer to Section 4.0 "Memory Organization" in this data sheet for device-specific register and bit information. The CPU module has a 16-bit (data) modified Harvard architecture with an enhanced instruction set, including significant support for DSP. The CPU has a 24-bit instruction word with a variable length opcode field. The Program Counter (PC) is 23 bits wide and addresses up to 4M x 24 bits of user program memory space. The actual amount of program memory implemented varies from device to device. A singlecycle instruction prefetch mechanism is used to help maintain throughput and provides predictable execution. All instructions execute in a single cycle, with the exception of instructions that change the program flow, the double-word move (MOV.D) instruction and the table instructions. Overhead-free program loop constructs are supported using the DO and REPEAT instructions, both of which are interruptible at any point. dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/ X04 devices have sixteen, 16-bit working registers in the programmer's model. Each of the working registers can serve as a data, address or address offset register. The sixteenth working register (W15) operates as a software Stack Pointer (SP) for interrupts and calls. There are two classes of instruction in the dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/ X04 devices: MCU and DSP. These two instruction classes are seamlessly integrated into a single CPU. The instruction set includes many addressing modes and is designed for optimum C compiler efficiency. For most instructions, the dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 is capable of executing a data (or program data) memory read, a working register (data) read, a data memory write and a program (instruction) memory read per instruction cycle. As a result, three parameter instructions can be supported, allowing A + B = C operations to be executed in a single cycle. (c) 2008-2012 Microchip Technology Inc. A block diagram of the CPU is shown in Figure 3-1, and the programmer's model is shown in Figure 3-2. 3.1 Data Addressing Overview The data space can be addressed as 32K words or 64 Kbytes and is split into two blocks, referred to as X and Y data memory. Each memory block has its own independent Address Generation Unit (AGU). The MCU class of instructions operates solely through the X memory AGU, which accesses the entire memory map as one linear data space. Certain DSP instructions operate through the X and Y AGUs to support dual operand reads, which splits the data address space into two parts. The X and Y data space boundary is device-specific. Overhead-free circular buffers (Modulo Addressing mode) are supported in both X and Y address spaces. The Modulo Addressing removes the software boundary checking overhead for DSP algorithms. Furthermore, the X AGU circular addressing can be used with any of the MCU class of instructions. The X AGU also supports Bit-Reversed Addressing to greatly simplify input or output data reordering for radix-2 FFT algorithms. The upper 32 Kbytes of the data space memory map can optionally be mapped into program space at any 16K program word boundary defined by the 8-bit Program Space Visibility Page (PSVPAG) register. The program-to-data space mapping feature allows any instruction access program space as if it were data space. 3.2 DSP Engine Overview The DSP engine features a high-speed, 17-bit by 17-bit multiplier, a 40-bit ALU, two 40-bit saturating accumulators and a 40-bit bidirectional barrel shifter. The barrel shifter is capable of shifting a 40-bit value up to 16 bits, right or left, in a single cycle. The DSP instructions operate seamlessly with all other instructions and have been designed for optimal realtime performance. The MAC instruction and other associated instructions can concurrently fetch two data operands from memory while multiplying two W registers and accumulating and optionally saturating the result in the same cycle. This instruction functionality requires that the RAM data space be split for these instructions and linear for all others. Data space partitioning is achieved in a transparent and flexible manner through dedicating certain working registers to each address space. DS70318F-page 29 dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 3.3 Special MCU Features The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/ X04 devices support 16/16 and 32/16 divide operations, both fractional and integer. All divide instructions are iterative operations. They must be executed within a REPEAT loop, resulting in a total execution time of 19 instruction cycles. The divide operation can be interrupted during any of those 19 cycles without loss of data. The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 devices feature a 17-bit by 17-bit single-cycle multiplier that is shared by both the MCU ALU and DSP engine. The multiplier can perform signed, unsigned and mixed sign multiplication. Using a 17-bit by 17-bit multiplier for 16-bit by 16-bit multiplication not only allows you to perform mixed sign multiplication, it also achieves accurate results for special operations, such as (-1.0) x (1.0). FIGURE 3-1: A 40-bit barrel shifter is used to perform up to a 16-bit left or right shift in a single cycle. The barrel shifter can be used by both MCU and DSP instructions. dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 CPU CORE BLOCK DIAGRAM PSV & Table Data Access Control Block Y Data Bus X Data Bus Interrupt Controller 8 16 16 16 16 Data Latch Data Latch X RAM Y RAM Address Latch Address Latch 23 23 PCU PCH PCL Program Counter Loop Stack Control Control Logic Logic 16 23 16 16 Address Generator Units Address Latch Program Memory EA MUX Data Latch ROM Latch 24 Instruction Reg 16 Literal Data Instruction Decode & Control 16 16 Control Signals to Various Blocks DSP Engine Divide Support 16 x 16 W Register Array 16 16-bit ALU 16 To Peripheral Modules DS70318F-page 30 (c) 2008-2012 Microchip Technology Inc. dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 FIGURE 3-2: dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 PROGRAMMER'S MODEL D15 D0 W0/WREG PUSH.S Shadow W1 DO Shadow W2 W3 Legend W4 DSP Operand Registers W5 W6 W7 Working Registers W8 W9 DSP Address Registers W10 W11 W12/DSP Offset W13/DSP Write Back W14/Frame Pointer W15/Stack Pointer Stack Pointer Limit Register SPLIM AD39 AD15 AD31 AD0 ACCA DSP Accumulators ACCB PC22 PC0 Program Counter 0 0 7 TBLPAG Data Table Page Address 7 0 PSVPAG Program Space Visibility Page Address 15 0 RCOUNT REPEAT Loop Counter 15 0 DCOUNT DO Loop Counter 22 0 DOSTART DO Loop Start Address DOEND DO Loop End Address 22 15 0 Core Configuration Register CORCON OA OB SA SB OAB SAB DA SRH (c) 2008-2012 Microchip Technology Inc.

Unless otherwise mentioned, arithmetic operations are 2's complement in nature. Depending on the operation, the ALU can affect the values of the Carry (C), Zero (Z), Negative (N), Overflow (OV) and Digit Carry (DC) Status bits in the SR register. The C and DC Status bits operate as Borrow and Digit Borrow bits, respectively, for subtraction operations. 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 saturation logic). The ALU can perform 8-bit or 16-bit operations, depending on the mode of the instruction that is used. Data for the ALU operation can come from the W register array or data memory, depending on the addressing mode of the instruction. Likewise, output data from the ALU can be written to the W register array or a data memory location. The DSP engine can also perform inherent accumulator-to-accumulator operations that require no additional data. These instructions are ADD, SUB and NEG. Refer to the "16-bit MCU and DSC Programmer's Reference Manual" (DS70157) for information on the SR bits affected by each instruction. The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/ X04 CPU incorporates hardware support for both multiplication and division. This includes a dedicated hardware multiplier and support hardware for 16-bit-divisor division. 3.5.1 MULTIPLIER Using the high-speed, 17-bit x 17-bit multiplier of the DSP engine, the ALU supports unsigned, signed or mixed sign operation in several MCU multiplication modes: * * * * * * * 16-bit x 16-bit signed 16-bit x 16-bit unsigned 16-bit signed x 5-bit (literal) unsigned 16-bit unsigned x 16-bit unsigned 16-bit unsigned x 5-bit (literal) unsigned 16-bit unsigned x 16-bit signed 8-bit unsigned x 8-bit unsigned 3.5.2 DIVIDER The divide block supports 32-bit/16-bit and 16-bit/16-bit signed and unsigned integer divide operations with the following data sizes: * * * * 32-bit signed/16-bit signed divide 32-bit unsigned/16-bit unsigned divide 16-bit signed/16-bit signed divide 16-bit unsigned/16-bit unsigned divide The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/ X04 is a single-cycle instruction flow architecture; therefore, concurrent operation of the DSP engine with MCU instruction flow is not possible. However, some MCU ALU and DSP engine resources can be used concurrently by the same instruction (for example, ED, EDAC). The DSP engine has options selected through bits in the CPU Core Control register (CORCON), as listed below: * * * * * * Fractional or integer DSP multiply (IF) Signed or unsigned DSP multiply (US) Conventional or convergent rounding (RND) Automatic saturation on/off for ACCA (SATA) Automatic saturation on/off for ACCB (SATB) Automatic saturation on/off for writes to data memory (SATDW) * Accumulator Saturation mode selection (ACCSAT) A block diagram of the DSP engine is shown in Figure 3-3. TABLE 3-1: Instruction DSP INSTRUCTIONS SUMMARY Algebraic Operation CLR A=0 ED EDAC MAC MAC MOVSAC MPY MPY MPY.N MSC A = (x - y)2 A = A + (x - y)2 A = A + (x * y) A = A + x2 No change in A A=x*y A=x2 A=-x*y A=A-x*y ACC Write Back Yes No No Yes No Yes No No No Yes The quotient for all divide instructions ends up in W0 and the remainder in W1. 16-bit signed and unsigned DIV instructions can specify any W register for both the 16-bit divisor (Wn) and any W register (aligned) pair (W(m + 1):Wm) for the 32-bit dividend. The divide algorithm takes one cycle per bit of divisor, so both 32-bit/ 16-bit and 16-bit/16-bit instructions take the same number of cycles to execute. (c) 2008-2012 Microchip Technology Inc.

Unsigned operands are zero-extended into the 17th bit of the multiplier input value. Signed operands are sign-extended into the 17th bit of the multiplier input value. The output of the 17-bit x 17-bit multiplier/scaler is a 33-bit value that is sign-extended to 40 bits. Integer data is inherently represented as a signed 2's complement value, where the Most Significant bit (MSb) is defined as a sign bit. The range of an N-bit 2's complement integer is -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 2,147,483,647 (0x7FFF FFFF). When the multiplier is configured for fractional multiplication, the data is represented as a 2's complement fraction, where the MSb is defined as a sign bit and the radix point is implied to lie just after the sign bit (QX format). The range of an N-bit 2'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 precision of 3.01518x10-5. In Fractional mode, the 16 x 16 multiply operation generates a 1.31 product that has a precision of 4.65661 x 10-10. The same multiplier is used to support the MCU multiply instructions, which include integer 16-bit signed, unsigned and mixed sign multiply operations. The MUL instruction can be directed to use byte or word-sized operands. Byte operands will direct a 16-bit result, and word operands will direct a 32-bit result to the specified register(s) in the W array. 3.6.2 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 preaccumulation source and post-accumulation destination. For the ADD and LAC instructions, the data to be accumulated or loaded can be optionally scaled using the barrel shifter prior to accumulation. (c) 2008-2012 Microchip Technology Inc. 3.6.2.1 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). * In the case of subtraction, 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 latched and reflected in the STATUS 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 that controls accumulator data saturation, if selected. It uses the result of the adder, the Overflow Status bits described previously and the SAT<A:B> (CORCON<7:6>) and ACCSAT (CORCON<4>) mode control bits to determine when and to what value to saturate. Six STATUS register bits support saturation and overflow: * OA: ACCA overflowed into guard bits * OB: ACCB overflowed into guard bits * SA: ACCA saturated (bit 31 overflow and saturation) or ACCA overflowed into guard bits and saturated (bit 39 overflow and saturation) * SB: ACCB saturated (bit 31 overflow and saturation) or ACCB overflowed into guard bits and saturated (bit 39 overflow and saturation) * OAB: Logical OR of OA and OB * 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 corresponding Overflow Trap Flag Enable bits (OVATE, OVBTE) in the INTCON1 register are set (refer to Section 7.0 "Interrupt Controller"). This allows the user application to take immediate action, for example, to correct system gain. DS70318F-page 37 dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 The SA and SB bits are modified each time data passes through the adder/subtracter, but can only be cleared by the user application. When set, they indicate that the accumulator has overflowed its maximum range (bit 31 for 32-bit saturation or bit 39 for 40-bit saturation) and will be saturated (if saturation is enabled). When saturation is not enabled, SA and SB default to bit 39 overflow and thus, indicate that a catastrophic overflow has occurred. If the COVTE bit in the INTCON1 register is set, SA and SB bits will generate an arithmetic warning trap when saturation is disabled. * W13, Register Direct: The rounded contents of the non-target accumulator are written into W13 as a 1.15 fraction. * [W13] + = 2, Register Indirect with Post-Increment: The rounded contents of the non-target accumulator are written into the address pointed to by W13 as a 1.15 fraction. W13 is then incremented by 2 (for a word write). The Overflow and Saturation Status bits can optionally be viewed in the STATUS Register (SR) as the logical OR of OA and OB (in bit OAB) and the logical OR of SA and SB (in bit SAB). Programmers can check one bit in the STATUS register to determine if either accumulator has overflowed, or one bit to determine if either accumulator has saturated. This is useful for complex number arithmetic, which typically uses both accumulators. The round logic is a combinational block that performs a conventional (biased) or convergent (unbiased) 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 that is passed to the data space write saturation logic. If rounding is not indicated by the instruction, a truncated 1.15 data value is stored and the least significant word is simply discarded. The device supports three Saturation and Overflow modes: * Bit 39 Overflow and Saturation: When bit 39 overflow and saturation occurs, the saturation logic loads the maximally positive 9.31 (0x7FFFFFFFFF) or maximally negative 9.31 value (0x8000000000) into the target accumulator. The SA or SB bit is set and remains set until cleared by the user application. This condition is referred to as `super saturation' and provides protection against erroneous data or unexpected algorithm problems (such as gain calculations). * Bit 31 Overflow and Saturation: When bit 31 overflow and saturation occurs, the saturation logic then loads the maximally positive 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 application. When this Saturation mode is in effect, the guard bits are not used, so the OA, OB or OAB bits are never set. * 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 application. 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 overflow can initiate a trap exception. 3.6.3 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 accumulator that is not targeted by the instruction into data space memory. The write is performed across the X bus into combined X and Y address space. The following addressing modes are supported: DS70318F-page 38 3.6.3.1 Round Logic Conventional rounding zero-extends bit 15 of the accumulator and adds it to the ACCxH word (bits 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 unchanged. A consequence of this algorithm 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. In this case, the Least Significant bit (bit 16 of the accumulator) of ACCxH is examined: * If it is `1', ACCxH is incremented. * If it is `0', ACCxH is not modified. Assuming that bit 16 is effectively random in nature, this scheme removes any rounding bias that may accumulate. The SAC and SAC.R instructions store either a truncated (SAC), or rounded (SAC.R) version of the contents of the target accumulator to data memory via the X bus, subject to data saturation (see Section 3.6.3.2 "Data Space Write Saturation"). For the MAC class of instructions, the accumulator writeback 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. (c) 2008-2012 Microchip Technology Inc. dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 3.6.3.2 Data Space Write Saturation 3.6.4 BARREL SHIFTER In addition to adder/subtracter saturation, writes to data space can 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 fractional 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 inputs are combined and used to select the appropriate 1.15 fractional value as output to write to data space memory. The barrel shifter can perform 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). If the SATDW bit in the CORCON register is set, data (after rounding or truncation) is tested for overflow and adjusted accordingly: The barrel shifter is 40 bits wide, thereby obtaining a 40-bit result for DSP shift operations and a 16-bit result for MCU shift operations. Data from the X bus is presented to the barrel shifter between bit positions 16 and 31 for right shifts, and between bit positions 0 and 16 for left shifts. * For input data greater than 0x007FFF, data written to memory is forced to the maximum positive 1.15 value, 0x7FFF. * For input data less than 0xFF8000, data written to memory is forced to the maximum negative 1.15 value, 0x8000. The shifter requires a signed binary value to determine both the magnitude (number of bits) and direction of the shift operation. A positive value shifts the operand right. A negative value shifts the operand left. A value of `0' does not modify the operand. The Most Significant bit of the source (bit 39) is used to determine the sign of the operand being tested. If the SATDW bit in the CORCON register is not set, the input data is always passed through unmodified under all conditions. (c) 2008-2012 Microchip Technology Inc.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 4. "Program Memory" (DS70202) in the "dsPIC33F/ PIC24H Family Reference Manual", which is available from the Microchip web site (www.microchip.com). The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/ X04 architecture features separate program and data memory spaces and buses. This architecture also allows the direct access to program memory from the data space during code execution. FIGURE 4-1: 4.1 Program Address Space The program address memory space of the dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/ X04 devices is 4M instructions. The space is addressable by a 24-bit value derived either from the 23-bit Program Counter (PC) during program execution, or from table operation or data space remapping as described in Section 4.6 "Interfacing Program and Data Memory Spaces". User application access to the program memory space is restricted to the lower half of the address range (0x000000 to 0x7FFFFF). The exception is the use of TBLRD/TBLWT operations, which use TBLPAG<7> to permit access to the Configuration bits and Device ID sections of the configuration memory space. The memory maps for the dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 devices are shown in Figure 4-1.

A hardware Reset vector is provided to redirect code execution from the default value of the PC on device Reset to the actual start of code. A GOTO instruction is programmed by the user application at 0x000000, with the actual address for the start of code at 0x000002. The program memory space is organized in wordaddressable blocks. Although it is treated as 24 bits wide, it is more appropriate consider each address of the program memory as a lower and upper word, with the upper byte of the upper word being unimplemented. The lower word always has an even address, while the upper word has an odd address (see Figure 4-2). The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/ X04 devices also have two interrupt vector tables, located from 0x000004 to 0x0000FF and 0x000100 to 0x0001FF. These vector tables allow each of the device interrupt sources to be handled by separate Interrupt Service Routines (ISRs). A more detailed discussion of the interrupt vector tables is provided in Section 7.1 "Interrupt Vector Table". Program memory addresses are always word-aligned on the lower word, and addresses are incremented or decremented by two during the code execution. This arrangement provides compatibility with data memory space addressing and makes data in the program memory space accessible.

The data space is accessed using separate Address Generation Units (AGUs) for read and write operations. The data memory maps is shown in Figure 4-3. All Effective Addresses (EAs) in the data memory space are 16 bits wide and point to bytes within the data space. This arrangement gives a data space address range of 64 Kbytes or 32K words. The lower half of the data memory space (that is, when EA<15> = 0) is used for implemented memory addresses, while the upper half (EA<15> = 1) is reserved for the Program Space Visibility area (see Section 4.6.3 "Reading Data from Program Memory Using Program Space Visibility"). All word accesses must be aligned to an even address. Misaligned word data fetches are not supported, so care must be taken when mixing byte and word operations, or translating from 8-bit MCU code. If a misaligned read or write is attempted, an address error trap is generated. If the error occurred on a read, the instruction underway is completed. If the error occurred on a write, the instruction is executed but the write does not occur. In either case, a trap is then executed, allowing the system and/or user application to examine the machine state prior to execution of the address Fault. All byte loads into any W register are loaded into the Least Significant Byte. The Most Significant Byte is not modified. dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/ X04 devices implement up to 2 Kbytes of data memory. Should an EA point to a location outside of this area, an all-zero word or byte will be returned. A sign-extend instruction (SE) is provided to allow user applications to translate 8-bit signed data to 16-bit signed values. Alternatively, for 16-bit unsigned data, user applications can clear the MSB of any W register by executing a zero-extend (ZE) instruction on the appropriate address. 4.2.1 4.2.3 DATA SPACE WIDTH The data memory space is organized in byte addressable, 16-bit wide blocks. Data is aligned in data memory and registers as 16-bit words, but all data space EAs resolve to bytes. The Least Significant Bytes (LSBs) of each word have even addresses, while the Most Significant Bytes (MSBs) have odd addresses. 4.2.2 DATA MEMORY ORGANIZATION AND ALIGNMENT To maintain backward compatibility with PIC(R) MCU devices and improve data space memory usage efficiency, the dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 instruction set supports both word and byte operations. As a consequence of byte accessibility, all effective address calculations are internally scaled to step through word-aligned memory. For example, the core recognizes that Post-Modified Register Indirect Addressing mode [Ws++] that results in a value of Ws + 1 for byte operations and Ws + 2 for word operations. Data byte reads will read the complete word that contains the byte, using the LSB of any EA to determine which byte to select. The selected byte is placed onto the LSB of the data path. 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 that matches the byte address. (c) 2008-2012 Microchip Technology Inc. SFR SPACE The first 2 Kbytes of the near data space, from 0x0000 to 0x07FF, is primarily occupied by Special Function Registers (SFRs). These are used by the dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/ X04 core and peripheral modules for controlling the operation of the device. SFRs are distributed among the modules that they control, and are generally grouped together by module. Much of the SFR space contains unused addresses; these are read as `0'. Note: 4.2.4 The actual set of peripheral features and interrupts varies by the device. Refer to the corresponding device tables and pinout diagrams for device-specific information. NEAR DATA SPACE The 8-Kbyte area between 0x0000 and 0x1FFF is referred to as the near data space. Locations in this space are directly addressable via a 13-bit absolute address field within all memory direct instructions. Additionally, the whole data space is addressable using MOV instructions, which support Memory Direct Addressing mode with a 16-bit address field, or by using Indirect Addressing mode using a working register as an Address Pointer.

These data spaces can be considered either separate (for some DSP instructions), or as one unified linear address range (for MCU instructions). The data spaces are accessed using two Address Generation Units (AGUs) and separate data paths. This feature allows certain instructions to concurrently fetch two words from RAM, thereby enabling efficient execution of DSP algorithms, such as Finite Impulse Response (FIR) filtering and Fast Fourier Transform (FFT). The X data space is used by all instructions and supports all addressing modes. X data space has separate read and write data buses. The X read data bus is the read data path for all instructions that view data space as combined X and Y address space. It is also the X data prefetch path for the dual operand DSP instructions (MAC class). (c) 2008-2012 Microchip Technology Inc. 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. Both the X and Y data spaces support Modulo Addressing mode for all instructions, subject to addressing mode restrictions. Bit-Reversed Addressing mode is only supported for writes to X data space. All data memory writes, including in DSP instructions, view data space as combined X and Y address space. The boundary between the X and Y data spaces is device-dependent and is not user-programmable. 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, though the implemented memory locations vary by device.

The Stack Pointer always points to the first available free word and grows from lower to higher addresses. It predecrements for stack pops and post-increments for stack pushes, as shown in Figure 4-6. For a PC push during any CALL instruction, the MSb of the PC is zero-extended before the push, ensuring that the MSb is always clear. Note: A PC push during exception processing concatenates the SRL register to the MSb of the PC prior to the push. The Stack Pointer Limit register (SPLIM) associated with the Stack Pointer sets an upper address boundary for the stack. SPLIM is uninitialized at Reset. As is the case for the Stack Pointer, SPLIM<0> is forced to `0' because all stack operations must be word-aligned. Whenever an EA is generated using W15 as a source or destination pointer, the resulting address is compared with the value in SPLIM. If the contents of the Stack Pointer (W15) and the SPLIM register are equal and a push operation is performed, a stack error trap will not occur. The stack error trap will occur on a subsequent push operation. For example, to cause a stack error trap when the stack grows beyond address 0x1000 in RAM, initialize the SPLIM with the value 0x0FFE. Similarly, a Stack Pointer underflow (stack error) trap is generated when the Stack Pointer address is found to be less than 0x0800. This prevents the stack from interfering with the Special Function Register (SFR) space. A write to the SPLIM register should not be immediately followed by an indirect read operation using W15. FIGURE 4-6: Stack Grows Toward Higher Address 0x0000 15 CALL STACK FRAME Instruction Addressing Modes The addressing modes shown in Table 4-48 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 differ from those in the other instruction types. 4.3.1 FILE REGISTER INSTRUCTIONS Most file register instructions use a 13-bit address field (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, which is denoted as WREG in these instructions. The destination is typically either the same file register or WREG (with the exception of the MUL instruction), which writes the result to a register or register pair. The MOV instruction allows additional flexibility and can access the entire data space. 4.3.2 MCU INSTRUCTIONS The three-operand MCU instructions are of the form: Operand 3 = Operand 1 <function> Operand 2 where, Operand 1 is always a working register (that is, 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 a data memory 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 Note: Not all instructions support all the addressing modes given above. Individual instructions can support different subsets of these addressing modes. 0 PC<15:0> 000000000 PC<22:16> <Free Word> W15 (before CALL) W15 (after CALL) POP : [--W15] PUSH : [W15++] (c) 2008-2012 Microchip Technology Inc. DS70318F-page 71 dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 TABLE 4-48: FUNDAMENTAL ADDRESSING MODES SUPPORTED 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 Effective Address (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 Indexed) Register Indirect with Literal Offset 4.3.3 The sum of Wn and a literal forms the EA. MOVE AND ACCUMULATOR INSTRUCTIONS Move instructions and the DSP accumulator class of instructions to provide a greater addressing flexibility than other instructions. In addition to the addressing modes supported by most MCU instructions, move and accumulator instructions also support Register Indirect with Register Offset Addressing mode, also referred to as Register Indexed mode. 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 by both source and destination (but typically only used by one). 4.3.4 The dual source operand DSP instructions (CLR, ED, EDAC, MAC, MPY, MPY.N, MOVSAC and MSC), also referred to as MAC instructions, use a simplified set of addressing modes to allow the user application to effectively manipulate the data pointers through register indirect tables. The two-source operand prefetch registers must be members of the set {W8, W9, W10, W11}. For data reads, W8 and W9 are always directed to the X RAGU, and 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 data space for W8 and W9 and Y data space for W10 and W11. Note: In summary, the following addressing modes are supported by move and accumulator instructions: * * * * * * * * Register Direct Register Indirect Register Indirect Post-modified Register Indirect Pre-modified Register Indirect with Register Offset (Indexed) Register Indirect with Literal Offset 8-bit Literal 16-bit Literal Note: Not all instructions support all the addressing modes given above. Individual instructions may support different subsets of these addressing modes. DS70318F-page 72 MAC INSTRUCTIONS Register Indirect with Register Offset Addressing mode is available only for W9 (in X space) and W11 (in Y space). 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) 4.3.5 OTHER INSTRUCTIONS Besides the addressing modes outlined previously, some instructions use literal constants of various sizes. For example, BRA (branch) instructions use 16-bit signed literals to specify the branch destination directly, 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 opcode itself. Certain operations, such as NOP, do not have any operands. (c) 2008-2012 Microchip Technology Inc. dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 4.4 Modulo Addressing Note: Modulo Addressing mode is a method used to provide an automated means to support circular data buffers using hardware. The objective is to remove the need for software 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 program space (since the data pointer mechanism is essentially the same for both). One circular buffer can be supported in each of the X (which also provides the pointers into program space) and Y data spaces. Modulo Addressing can operate on any W register pointer. However, it is not advisable to use W14 or W15 for Modulo Addressing since these two registers are used as the Stack Frame Pointer and Stack Pointer, respectively. In general, any particular circular buffer can be configured to operate in only one direction as there are certain restrictions on the buffer start address (for incrementing buffers), or end address (for decrementing buffers), based upon the direction of the buffer. The only exception to the usage restrictions is for buffers that have a power-of-two length. As these buffers satisfy the start and end address criteria, they can operate in a bidirectional mode (that is, address boundary checks are performed on both the lower and upper address boundaries). 4.4.1 START AND END ADDRESS The Modulo Addressing scheme requires that a starting and ending address be specified and loaded into the 16-bit Modulo Buffer Address registers: XMODSRT, XMODEND, YMODSRT and YMODEND (see Table 4-1). FIGURE 4-7: Y space Modulo Addressing EA calculations assume word-sized data (LSb of every EA is always clear). The length of a circular buffer is not directly specified. It is determined by the difference between the corresponding start and end addresses. The maximum possible length of the circular buffer is 32K words (64 Kbytes). 4.4.2 W ADDRESS REGISTER SELECTION The Modulo and Bit-Reversed Addressing Control register, MODCON<15:0>, contains enable flags as well as a W register field to specify the W Address registers. The XWM and YWM fields select the registers that will operate with Modulo Addressing: * If XWM = 15, X RAGU and X WAGU Modulo Addressing is disabled. * 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 4-1). Modulo Addressing is enabled for X data space when XWM is set to any value 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>.

DS70318F-page 73 dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 4.4.3 MODULO ADDRESSING APPLICABILITY Modulo Addressing can be applied to the Effective Address (EA) calculation associated with any W register. Address boundaries check for addresses equal to: * The upper boundary addresses for incrementing buffers * The lower boundary addresses for decrementing buffers The address boundaries check for addresses less than or greater than the upper (for incrementing buffers) and lower (for decrementing buffers) boundary addresses (not just equal to). Address changes can, therefore, jump beyond boundaries and still be adjusted correctly. Note: The modulo corrected effective address is written back to the register only when PreModify or Post-Modify Addressing mode is used to compute the effective address. When an address offset (such as [W7 + W2]) is used, Modulo Addressing correction is performed but the contents of the register remain unchanged. If the length of a bit-reversed buffer is M = 2N bytes, the last `N' bits of the data buffer start address must be zeros. XB<14:0> is the Bit-Reversed Address modifier, or `pivot point,' which is typically a constant. In the case of an FFT computation, its value is equal to half of the FFT data buffer size. Note: When enabled, Bit-Reversed Addressing is executed only for Register Indirect with Pre-Increment or PostIncrement Addressing and word-sized data writes. It will not function for any other addressing mode or for byte-sized data, and normal addresses are generated instead. When Bit-Reversed Addressing is active, the W Address Pointer is always added to the address modifier (XB), and the offset associated with the Register Indirect Addressing mode is ignored. In addition, as word-sized data is a requirement, the LSb of the EA is ignored (and always clear). Note: 4.5 Bit-Reversed Addressing Bit-Reversed Addressing mode is intended to simplify data re-ordering for radix-2 FFT algorithms. It is supported by the X AGU for data writes only. The modifier, which can be a constant value or register contents, is regarded as having its bit order reversed. The address source and destination are kept in normal order. Thus, the only operand requiring reversal is the modifier. 4.5.1 BIT-REVERSED ADDRESSING IMPLEMENTATION 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. Modulo Addressing and Bit-Reversed Addressing should not be enabled together. If an application attempts to do so, Bit-Reversed Addressing will assume priority when active for the X WAGU and X WAGU; Modulo Addressing will be disabled. However, Modulo Addressing will continue to function in the X RAGU. If Bit-Reversed Addressing has already been enabled by setting the BREN (XBREV<15>) bit, 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. Bit-Reversed Addressing mode is enabled in any of these situations: * BWM bits (W register selection) in the MODCON register are any value other than 15 (the stack cannot be accessed using Bit-Reversed Addressing) * The BREN bit is set in the XBREV register * The addressing mode used is Register Indirect with Pre-Increment or Post-Increment DS70318F-page 74 (c) 2008-2012 Microchip Technology Inc. dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 FIGURE 4-8: BIT-REVERSED ADDRESS EXAMPLE Sequential Address b15 b14 b13 b12 b11 b10 b9 b8 b7 b6 b5 b4 b3 b2 b1 0 Bit Locations Swapped Left-to-Right Around Center of Binary Value b15 b14 b13 b12 b11 b10 b9 b8 b7 b6 b5 b1 b2 b3 b4 0 Bit-Reversed Address Pivot Point XB = 0x0008 for a 16-Word Bit-Reversed Buffer TABLE 4-49: BIT-REVERSED ADDRESS SEQUENCE (16-ENTRY) Normal Address Bit-Reversed Address A3 A2 A1 A0 Decimal A3 A2 A1 A0 Decimal 0 0 0 0 0 0 0 0 0 0 0 0 0 1 1 1 0 0 0 8 0 0 1 0 2 0 1 0 0 4 0 0 1 1 3 1 1 0 0 12 0 1 0 0 4 0 0 1 0 2 0 1 0 1 5 1 0 1 0 10 0 1 1 0 6 0 1 1 0 6 0 1 1 1 7 1 1 1 0 14 1 0 0 0 8 0 0 0 1 1 1 0 0 1 9 1 0 0 1 9 1 0 1 0 10 0 1 0 1 5 1 0 1 1 11 1 1 0 1 13 1 1 0 0 12 0 0 1 1 3 1 1 0 1 13 1 0 1 1 11 1 1 1 0 14 0 1 1 1 7 1 1 1 1 15 1 1 1 1 15 (c) 2008-2012 Microchip Technology Inc. DS70318F-page 75 dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 4.6 Interfacing Program and Data Memory Spaces 4.6.1 The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/ X04 architecture uses a 24-bit-wide program space and a 16-bit-wide data space. The architecture is also a modified Harvard scheme, meaning that data can also be present in the program space. To use this data successfully, it must be accessed in a way that preserves the alignment of information in both spaces. For table operations, the 8-bit Table Page register (TBLPAG) is used to define a 32K word region within the program space. This is concatenated with a 16-bit EA to arrive at a full 24-bit program space address. In this format, the Most Significant bit of TBLPAG is used to determine if the operation occurs in the user memory (TBLPAG<7> = 0) or the configuration memory (TBLPAG<7> = 1). Aside from normal execution, the dsPIC33FJ06GS101/ X02 and dsPIC33FJ16GSX02/X04 architecture provides two methods by which program space can be accessed during operation: * Using table instructions to access individual bytes or words anywhere in the program space * Remapping a portion of the program space into the data space (Program Space Visibility) For remapping operations, the 8-bit Program Space Visibility Register (PSVPAG) is used to define a 16K word page in the program space. When the Most Significant bit of the EA is `1', PSVPAG is concatenated with the lower 15 bits of the EA to form a 23-bit program space address. Unlike table operations, this limits remapping operations strictly to the user memory area. Table instructions allow an application to read or write to small areas of the program memory. This capability makes the method ideal for accessing data tables that need to be updated periodically. It also allows access to all bytes of the program word. The remapping method allows an application to access a large block of data on a read-only basis, which is ideal for look ups from a large table of static data. The application can only access the least significant word of the program word. TABLE 4-50: Table 4-50 and Figure 4-9 show how the program EA is created for table operations and remapping accesses from the data EA. Here, P<23:0> refers to a program space word, and D<15:0> refers to a data space word.

The TBLRDH and TBLWTH instructions are the only method to read or write the upper 8 bits of a program space word 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 wide word address spaces, residing side by side, each with the same address range. TBLRDL and TBLWTL access the space that contains the least significant data word. TBLRDH and TBLWTH access the space that contains the upper data byte. Two table instructions are provided to move byte or word-sized (16-bit) data to and from program space. Both function as either byte or word operations. * TBLRDL (Table Read Low): - In Word mode, this instruction maps the lower word of the program space location (P<15:0>) to a data address (D<15:0>). FIGURE 4-10: - In Byte mode, either the upper or lower byte of the lower program word is mapped to the lower byte of a data address. The upper byte is selected when byte select is `1'; the lower byte is selected when it is `0'. * TBLRDH (Table Read High): - In Word mode, this instruction maps the entire upper word of a program address (P<23:16>) to a data address. Note that D<15:8>, the `phantom byte', will always be `0'. - In Byte mode, this instruction maps the upper or lower byte of the program word to D<7:0> of the data address, in the TBLRDL instruction. The data is always `0' when the upper `phantom' byte is selected (Byte Select = 1). Similarly, two table instructions, TBLWTH and TBLWTL, are used to write individual bytes or words to a program space address. The details of their operation are explained in Section 5.0 "Flash Program Memory". For all table operations, the area of program memory space to be accessed is determined by the Table Page register (TBLPAG). TBLPAG covers the entire program memory space of the device, including user and configuration spaces. When TBLPAG<7> = 0, the table page is located in the user memory space. When TBLPAG<7> = 1, the page is located in configuration space.

Only read operations are shown; write operations are also valid in the user memory area.

This option provides transparent access to stored constant data from the data space without the need to use special instructions (such as TBLRDL/H). Program space access through the data space occurs if the Most Significant bit of the data space EA is `1' and program space visibility is enabled by setting the PSV bit in the Core Control register (CORCON<2>). The location of the program memory space to be mapped into the data space is determined by the Program Space Visibility Page register (PSVPAG). This 8-bit register defines any one of 256 possible pages of 16K words in program space. In effect, PSVPAG functions as the upper 8 bits of the program memory address, with the 15 bits of the EA functioning as the lower bits. By incrementing the PC by 2 for each program memory word, the lower 15 bits of data space addresses directly map to the lower 15 bits in the corresponding program space addresses. Data reads to this area add a cycle to the instruction being executed, since two program memory fetches are required. Although each data space address 8000h and higher maps directly into a corresponding program memory address (see Figure 4-11), only the lower 16 bits of the FIGURE 4-11: 24-bit program word are used to contain the data. The upper 8 bits of any program space location used as data should be programmed with `1111 1111' or `0000 0000' to force a NOP. This prevents possible issues should the area of code ever be accidentally executed. Note: PSV access is temporarily disabled during table reads/writes. For operations that use PSV and are executed outside a REPEAT loop, the MOV and MOV.D instructions require one instruction cycle in addition to the specified execution time. All other instructions require two instruction cycles in addition to the specified execution time. For operations that use PSV, and are executed inside a REPEAT loop, these instances require two instruction cycles in addition to the 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 interrupt is serviced Any other iteration of the REPEAT loop will allow the instruction using PSV to access data, to execute in a single cycle.

This corresponds exactly to the same lower 15 bits of the actual program space address.

This allows customers to manufacture boards with unprogrammed devices and then program the digital signal controller just before shipping the product. This also allows the most recent firmware or a custom firmware to be programmed. Note 1: This data sheet summarizes the features of the dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 families of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 5. "Flash Programming" (DS70191) in the "dsPIC33F/PIC24H Family Reference Manual", which is available from the Microchip web site (www.microchip.com). RTSP is accomplished using TBLRD (table read) and TBLWT (table write) instructions. With RTSP, the user application can write program memory data, either in blocks or `rows' of 64 instructions (192 bytes) at a time, or a single program memory word, and erase program memory in blocks or `pages' of 512 instructions (1536 bytes) at a time. 2: Some registers and associated bits described in this section may not be available on all devices. Refer to Section 4.0 "Memory Organization" in this data sheet for device-specific register and bit information. 5.1 The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/ X04 devices contain internal Flash program memory for storing and executing application code. The memory is readable, writable and erasable during normal operation over the entire VDD range. Flash memory can be programmed in two ways: Regardless of the method used, all programming of Flash memory is done with the table read and table write instructions. These allow direct read and write access to the program memory space from the data memory while the device is in normal operating mode. The 24-bit target address in the program memory 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. 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 both Word and Byte modes. * In-Circuit Serial ProgrammingTM (ICSPTM) programming capability * Run-Time Self-Programming (RTSP) ICSP allows a dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 device to be serially programmed while in the end application circuit. This is done with two lines for programming clock and programming data (one of the alternate programming pin pairs: PGECx/PGEDx, and three other lines for FIGURE 5-1: Table Instructions and Flash Programming The TBLRDH and TBLWTH instructions are used to read or write to bits<23:16> of program memory.

RTSP allows the user application to erase a page of memory, which consists of eight rows (512 instructions) at a time, and to program one row or one word at a time. Table 24-12 shows typical erase and programming times. The 8-row erase pages and single row write rows are edge-aligned from the beginning of program memory, on boundaries of 1536 bytes and 192 bytes, respectively. The program memory implements holding buffers that can contain 64 instructions of programming data. Prior to the actual programming operation, the write data must be loaded into the buffers sequentially. The instruction words loaded must always be from a group of 64 boundary. The basic sequence for RTSP programming is to set up a Table Pointer, then do a series of TBLWT instructions to load the buffers. Programming is performed by setting the control bits in the NVMCON register. A total of 64 TBLWTL and TBLWTH instructions are required to load the instructions. All of the table write operations are single-word writes (two instruction cycles) because only the buffers are written. A programming cycle is required for programming each row. 5.3 Programming Operations A complete programming sequence is necessary for programming or erasing the internal Flash in RTSP mode. The processor stalls (waits) until the programming operation is finished. The programming time depends on the FRC accuracy (see Table 24-20) and the value of the FRC Oscillator Tuning register (see Register 8-4). Use the following formula to calculate the minimum and maximum values for the Row Write Time, Page Erase Time, and Word Write Cycle Time parameters (see Table 24-12). EQUATION 5-1: PROGRAMMING TIME T ------------------------------------------------------------------------------------------------------------------------7.37 MHz x ( FRC Accuracy )% x ( FRC Tuning )% For example, if the device is operating at +125C, the FRC accuracy will be 5%. If the TUN<5:0> bits (see Register 8-4) are set to `b111111, the minimum row write time is equal to Equation 5-2. EQUATION 5-2: MINIMUM ROW WRITE TIME 11064 Cycles T RW = ---------------------------------------------------------------------------------------------- = 1.435ms 7.37 MHz x ( 1 + 0.05 ) x ( 1 - 0.00375 ) The maximum row write time is equal to Equation 5-3. EQUATION 5-3: MAXIMUM ROW WRITE TIME 11064 Cycles T RW = ---------------------------------------------------------------------------------------------- = 1.586ms 7.37 MHz x ( 1 - 0.05 ) x ( 1 - 0.00375 ) Setting the WR bit (NVMCON<15>) starts the operation, and the WR bit is automatically cleared when the operation is finished. 5.4 Control Registers Two SFRs are used to read and write the program Flash memory: NVMCON and NVMKEY. The NVMCON register (Register 5-1) controls which blocks are to be erased, which memory type is to be programmed and the start of the programming cycle. NVMKEY is a write-only register that is used for write protection. To start a programming or erase sequence, the user application must consecutively write 0x55 and 0xAA to the NVMKEY register. Refer to Section 5.3 "Programming Operations" for further details.

One row of program Flash memory can be programmed at a time. To achieve this, it is necessary to erase the 8-row erase page that contains the desired row. The general process is: 1. 2. 3. Read eight rows of program memory (512 instructions) and store in data RAM. Update the program data in RAM with the desired new data. Erase the block (see Example 5-1): a) Set the NVMOP<3:0> bits (NVMCON<3:0>) to `0010' to configure for block erase. Set the ERASE (NVMCON<6>) and WREN (NVMCON<14>) bits. b) Write the starting address of the page to be erased into the TBLPAG and W registers. c) Write 0x55 to NVMKEY. d) Write 0xAA to NVMKEY. e) Set the WR bit (NVMCON<15>). The erase cycle begins and the CPU stalls for the duration of the erase cycle. When the erase is done, the WR bit is cleared automatically. EXAMPLE 5-1: For protection against accidental operations, the write initiate sequence for the NVMKEY register must be used to allow any erase or program operation to proceed. After the programming command has been executed, the user application must wait for the programming time until programming is complete. The two instructions following the start of the programming sequence should be NOPs, as shown in Example 5-3. ERASING A PROGRAM MEMORY PAGE ; Set up NVMCON for block erase operation MOV #0x4042, W0 MOV W0, NVMCON ; Init pointer to row to be ERASED MOV #tblpage(PROG_ADDR), W0 MOV W0, TBLPAG MOV #tbloffset(PROG_ADDR), W0 TBLWTL W0, [W0] DISI #5 MOV MOV MOV MOV BSET NOP NOP 6. Write the first 64 instructions from data RAM into the program memory buffers (see Example 5-2). Write the program block to Flash memory: a) Set the NVMOP<3:0> bits to `0001' to configure for row programming.

The programming cycle begins and the CPU stalls for the duration of the write cycle. When the write to Flash memory is done, the WR bit is cleared automatically. Repeat steps 4 and 5, using the next available 64 instructions from the block in data RAM by incrementing the value in the TBLPAG register, until all 512 instructions are written back to Flash memory. #0x55, W0 W0, NVMKEY #0xAA, W1 W1, NVMKEY NVMCON, #WR (c) 2008-2012 Microchip Technology Inc. ; ; Initialize NVMCON ; ; ; ; ; ; ; ; ; ; ; ; Initialize PM Page Boundary SFR Initialize in-page EA[15:0] pointer Set base address of erase block Block all interrupts with priority <7 for next 5 instructions Write the 55 key Write the AA key Start the erase sequence Insert two NOPs after the erase command is asserted DS70318F-page 85 dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 EXAMPLE 5-2: LOADING THE WRITE BUFFERS ; Set up NVMCON for row programming operations MOV #0x4001, W0 ; MOV W0, NVMCON ; Initialize NVMCON ; Set up a pointer to the first program memory location to be written ; program memory selected, and writes enabled MOV #0x0000, W0 ; MOV W0, TBLPAG ; Initialize PM Page Boundary SFR MOV #0x6000, W0 ; An example program memory address ; Perform the TBLWT instructions to write the latches ; 0th_program_word MOV #LOW_WORD_0, W2 ; MOV #HIGH_BYTE_0, W3 ; TBLWTL W2, [W0] ; Write PM low word into program latch TBLWTH W3, [W0++] ; Write PM high byte into program latch ; 1st_program_word MOV #LOW_WORD_1, W2 ; MOV #HIGH_BYTE_1, W3 ; TBLWTL W2, [W0] ; Write PM low word into program latch TBLWTH W3, [W0++] ; Write PM high byte into program latch ; 2nd_program_word MOV #LOW_WORD_2, W2 ; MOV #HIGH_BYTE_2, W3 ; TBLWTL W2, [W0] ; Write PM low word into program latch TBLWTH W3, [W0++] ; Write PM high byte into program latch * * * ; 63rd_program_word MOV #LOW_WORD_31, W2 ; MOV #HIGH_BYTE_31, W3 ; TBLWTL W2, [W0] ; Write PM low word into program latch TBLWTH W3, [W0++] ; Write PM high byte into program latch EXAMPLE 5-3: INITIATING A PROGRAMMING SEQUENCE DISI #5 MOV MOV MOV MOV BSET NOP NOP #0x55, W0 W0, NVMKEY #0xAA, W1 W1, NVMKEY NVMCON, #WR DS70318F-page 86 ; Block all interrupts with priority <7 ; for next 5 instructions ; ; ; ; ; ; Write the 55 key Write the AA key Start the erase sequence Insert two NOPs after the erase command is asserted (c) 2008-2012 Microchip Technology Inc. dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 6.0 RESETS A simplified block diagram of the Reset module is shown in Figure 6-1. Note 1: This data sheet summarizes the features of the dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 families of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 8. "Reset" (DS70192) in the "dsPIC33F/PIC24H Family Reference Manual", which is available from the Microchip web site (www.microchip.com). 2: Some registers and associated bits described in this section may not be available on all devices. Refer to Section 4.0 "Memory Organization" in this data sheet for device-specific register and bit information. The Reset module combines all Reset sources and controls the device Master Reset Signal, SYSRST. The following is a list of device Reset sources: * * * * * * * * POR: Power-on Reset BOR: Brown-out Reset MCLR: Master Clear Pin Reset SWR: Software RESET Instruction WDTO: Watchdog Timer Reset CM: Configuration Mismatch Reset TRAPR: Trap Conflict Reset IOPUWR: Illegal Condition Device Reset - Illegal Opcode Reset - Uninitialized W Register Reset - Security Reset FIGURE 6-1: Any active source of reset will make the SYSRST signal active. On system Reset, some of the registers associated with the CPU and peripherals are forced to a known Reset state and some are unaffected. Note: Refer to the specific peripheral section or Section 3.0 "CPU" of this data sheet for register Reset states. All types of device Reset sets a corresponding status bit in the RCON register to indicate the type of Reset (see Register 6-1). A POR clears all the bits, except for the POR bit (RCON<0>), that are set. The user application can set or clear any bit at any time during code execution. The RCON bits only serve as status bits. Setting a particular Reset status bit in software does not cause a device Reset to occur. The RCON register also has other bits associated with the Watchdog Timer and device power-saving states. The function of these bits is discussed in other sections of this manual. Note: The status bits in the RCON register should be cleared after they are read so that the next RCON register value after a device Reset is meaningful.

DS70318F-page 89 dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 6.1 System Reset * Cold Reset * Warm Reset A warm Reset is the result of all the other Reset sources, including the RESET instruction. On warm Reset, the device will continue to operate from the current clock source as indicated by the Current Oscillator Selection (COSC<2:0>) bits in the Oscillator Control (OSCCON<14:12>) register. A cold Reset is the result of a Power-on Reset (POR) or a Brown-out Reset (BOR). On a cold Reset, the FNOSC Configuration bits in the FOSC Configuration register select the device clock source. The device is kept in a Reset state until the system power supplies have stabilized at appropriate levels and the oscillator clock is ready. The sequence in which this occurs is detailed in Figure 6-2. The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/ X04 families of devices have two types of Reset: TABLE 6-1: OSCILLATOR DELAY Oscillator Mode Oscillator Startup Delay Oscillator Startup Timer PLL Lock Time Total Delay FRC, FRCDIV16, FRCDIVN TOSCD(1) -- -- TOSCD(1) FRCPLL TOSCD(1) -- TLOCK(3) TOSCD + TLOCK(1,3) XT TOSCD(1) -- TOSCD + TOST(1,2) HS TOSCD(1) TOST(2) TOST(2) -- TOSCD + TOST(1,2) EC -- -- -- -- XTPLL TOSCD(1) TOST(2) TLOCK(3) TOSCD + TOST + TLOCK(1,2,3) HSPLL TOSCD(1) TOST(2) TLOCK(3) TOSCD + TOST + TLOCK(1,2,3) ECPLL -- -- TLOCK(3) TLOCK(3) LPRC TOSCD(1) -- -- TOSCD(1) Note 1: 2: 3: TOSCD = Oscillator start-up delay (1.1 s max for FRC, 70 s max for LPRC). Crystal oscillator start-up times vary with crystal characteristics, load capacitance, etc. TOST = Oscillator start-up timer delay (1024 oscillator clock period). For example, TOST = 102.4 s for a 10 MHz crystal and TOST = 32 ms for a 32 kHz crystal. TLOCK = PLL lock time (1.5 ms nominal) if PLL is enabled.

The POR circuit is active until VDD crosses the VPOR threshold and the delay, TPOR, has elapsed. 2: BOR Reset: The on-chip voltage regulator has a BOR circuit that keeps the device in Reset until VDD crosses the VBOR threshold and the delay, TBOR, has elapsed. The delay, TBOR, ensures the voltage regulator output becomes stable. 3: PWRT Timer: The programmable power-up timer continues to hold the processor in Reset for a specific period of time (TPWRT) after a BOR. The delay, TPWRT, ensures that the system power supplies have stabilized at the appropriate level for full-speed operation. After the delay, TPWRT has elapsed and the SYSRST becomes inactive, which in turn, enables the selected oscillator to start generating clock cycles. 4: Oscillator Delay: The total delay for the clock to be ready for various clock source selections is given in Table 6-1. Refer to Section 8.0 "Oscillator Configuration" for more information. 5: When the oscillator clock is ready, the processor begins execution from location 0x000000. The user application programs a GOTO instruction at the Reset address, which redirects program execution to the appropriate start-up routine. 6: If the Fail-Safe Clock Monitor (FSCM) is enabled, it begins to monitor the system clock when the system clock is ready and the delay, TFSCM, has elapsed.

Note: When the device exits the Reset condition (begins normal operation), the device operating parameters (voltage, frequency, temperature, etc.) must be within their operating ranges; otherwise, the device may not function correctly. The user application must ensure that the delay between the time power is first applied, and the time SYSRST becomes inactive, is long enough to get all operating parameters within specification. DS70318F-page 91 dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 6.2 Power-on Reset (POR) A Power-on Reset (POR) circuit ensures the device is reset from power-on. The POR circuit is active until VDD crosses the VPOR threshold and the delay, TPOR, has elapsed. The delay, TPOR, ensures the internal device bias circuits become stable. The device supply voltage characteristics must meet the specified starting voltage and rise rate requirements to generate the POR. Refer to Section 24.0 "Electrical Characteristics" for details. The POR status (POR) bit in the Reset Control (RCON<0>) register is set to indicate the Power-on Reset. 6.2.1 Brown-out Reset (BOR) and Power-up Timer (PWRT) The on-chip regulator has a Brown-out Reset (BOR) circuit that resets the device when the VDD is too low (VDD < VBOR) for proper device operation. The BOR circuit keeps the device in Reset until VDD crosses the FIGURE 6-3: VBOR threshold and the delay, TBOR, has elapsed. The delay, TBOR, ensures the voltage regulator output becomes stable. The BOR status (BOR) bit in the Reset Control (RCON<1>) register is set to indicate the Brown-out Reset. The device will not run at full speed after a BOR as the VDD should rise to acceptable levels for full-speed operation. The PWRT provides power-up time delay (TPWRT) to ensure that the system power supplies have stabilized at the appropriate levels for full-speed operation before the SYSRST is released. The power-up timer delay (TPWRT) is programmed by the Power-on Reset Timer Value Select (FPWRT<2:0>) bits in the POR Configuration (FPOR<2:0>) register, which provides eight settings (from 0 ms to 128 ms). Refer to Section 21.0 "Special Features" for further details. Figure 6-3 shows the typical brown-out scenarios. The reset delay (TBOR + TPWRT) is initiated each time VDD rises above the VBOR trip point. BROWN-OUT SITUATIONS VDD VBOR TBOR + TPWRT SYSRST VDD VBOR TBOR + TPWRT SYSRST VDD dips before PWRT expires VDD VBOR TBOR + TPWRT SYSRST DS70318F-page 92 (c) 2008-2012 Microchip Technology Inc. dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 6.3 External Reset (EXTR) The external Reset is generated by driving the MCLR pin low. The MCLR pin is a Schmitt trigger input with an additional glitch filter. Reset pulses that are longer than the minimum pulse width will generate a Reset. Refer to Section 24.0 "Electrical Characteristics" for minimum pulse width specifications. The external Reset (MCLR) pin (EXTR) bit in the Reset Control (RCON) register is set to indicate the MCLR Reset. 6.3.0.1 EXTERNAL SUPERVISORY CIRCUIT Many systems have external supervisory circuits that generate Reset signals to reset multiple devices in the system. This external Reset signal can be directly connected to the MCLR pin to reset the device when the rest of system is reset. 6.3.0.2 INTERNAL SUPERVISORY CIRCUIT When using the internal power supervisory circuit to reset the device, the external Reset pin (MCLR) should be tied directly or resistively to VDD. In this case, the MCLR pin will not be used to generate a Reset. The external Reset pin (MCLR) does not have an internal pull-up and must not be left unconnected. 6.4 Software RESET Instruction (SWR) Whenever the RESET instruction is executed, the device will assert SYSRST, placing the device in a special Reset state. This Reset state will not re-initialize the clock. The clock source in effect prior to the RESET instruction will remain. SYSRST is released at the next instruction cycle and the Reset vector fetch will commence. The Software Reset (SWR) flag (instruction) in the Reset Control (RCON<6>) register is set to indicate the software Reset. 6.5 Watchdog Time-out Reset (WDTO) Whenever a Watchdog time-out occurs, the device will asynchronously assert SYSRST. The clock source will remain unchanged. A WDT time-out during Sleep or Idle mode will wake-up the processor, but will not reset the processor. The Watchdog Timer Time-out (WDTO) flag in the Reset Control (RCON<4>) register is set to indicate the Watchdog Reset. Refer to Section 21.4 "Watchdog Timer (WDT)" for more information on Watchdog Reset. (c) 2008-2012 Microchip Technology Inc. 6.6 Trap Conflict Reset If a lower priority hard trap occurs while a higher priority trap is being processed, a hard Trap Conflict Reset occurs. The hard traps include exceptions of priority level 13 through level 15, inclusive. The address error (level 13) and oscillator error (level 14) traps fall into this category. The Trap Reset (TRAPR) flag in the Reset Control (RCON<15>) register is set to indicate the Trap Conflict Reset. Refer to Section 7.0 "Interrupt Controller" for more information on Trap Conflict Resets. 6.7 Configuration Mismatch Reset To maintain the integrity of the Peripheral Pin Select Control registers, they are constantly monitored with shadow registers in hardware. If an unexpected change in any of the registers occur (such as cell disturbances caused by ESD or other external events), a Configuration Mismatch Reset occurs. The Configuration Mismatch (CM) flag in the Reset Control (RCON<9>) register is set to indicate the Configuration Mismatch Reset. Refer to Section 10.0 "I/O Ports" for more information on the Configuration Mismatch Reset. Note: 6.8 The Configuration Mismatch Reset feature and associated Reset flag are not available on all devices. Illegal Condition Device Reset An illegal condition device Reset occurs due to the following sources: * Illegal Opcode Reset * Uninitialized W Register Reset * Security Reset The Illegal Opcode or Uninitialized W Access Reset (IOPUWR) flag in the Reset Control (RCON<14>) register is set to indicate the illegal condition device Reset. 6.8.1 ILLEGAL OPCODE RESET A device Reset is generated if the device attempts to execute an illegal opcode value that is fetched from program memory. The Illegal Opcode Reset function can prevent the device from executing program memory sections that are used to store constant data. To take advantage of the Illegal Opcode Reset, use only the lower 16 bits of each program memory section to store the data values. The upper 8 bits should be programmed with 3Fh, which is an illegal opcode value. DS70318F-page 93 dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 6.8.2 UNINITIALIZED W REGISTER RESET The VFC occurs when the program counter is reloaded with an interrupt or trap vector. Any attempt to use the uninitialized W register as an Address Pointer will Reset the device. The W register array (with the exception of W15) is cleared during all Resets and is considered uninitialized until written to. 6.8.3 6.9 SECURITY RESET If a Program Flow Change (PFC) or Vector Flow Change (VFC) targets a restricted location in a protected segment (boot and secure segment), that operation will cause a Security Reset. The PFC occurs when the program counter is reloaded as a result of a call, jump, computed jump, return, return from subroutine or other form of branch instruction. TABLE 6-3: Refer to Section 21.8 "Code Protection and CodeGuardTM Security" for more information on Security Reset. Using the RCON Status Bits The user application can read the Reset Control (RCON) register after any device Reset to determine the cause of the Reset. Note: The status bits in the RCON register should be cleared after they are read so that the next RCON register value after a device Reset will be meaningful. Table 6-3 provides a summary of the Reset flag bit operation.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 41. "Interrupts (Part IV)" (DS70300) in the "dsPIC33F/ PIC24H Family Reference Manual", which is available on the Microchip web site (www.microchip.com). 2: Some registers and associated bits described in this section may not be available on all devices. Refer to Section 4.0 "Memory Organization" in this data sheet for device-specific register and bit information. The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/ X04 interrupt controller reduces the numerous peripheral interrupt request signals to a single interrupt request signal to the dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 CPU. It has the following features: * Up to eight processor exceptions and software traps * Seven user-selectable priority levels * Interrupt Vector Table (IVT) with up to 118 vectors * A unique vector for each interrupt or exception source * Fixed priority within a specified user priority level * Alternate Interrupt Vector Table (AIVT) for debug support * Fixed interrupt entry and return latencies 7.1 Interrupt Vector Table The Interrupt Vector Table (IVT) is shown in Figure 7-1. The IVT resides in program memory, starting at location 000004h. The IVT contains 126 vectors, consisting of eight nonmaskable trap vectors, plus up to 118 sources of interrupt. In general, each interrupt source has its own vector. Each interrupt vector contains a 24-bit-wide address. The value programmed into each interrupt vector location is the starting address of the associated Interrupt Service Routine (ISR). (c) 2008-2012 Microchip Technology Inc. Interrupt vectors are prioritized in terms of their natural priority. This priority is linked to their position in the vector table. Lower addresses generally have a higher natural priority. For example, the interrupt associated with vector 0 will take priority over interrupts at any other vector address. The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/ X04 devices implement up to 35 unique interrupts and 4 non-maskable traps. These are summarized in Table 7-1. 7.1.1 ALTERNATE INTERRUPT VECTOR TABLE The Alternate Interrupt Vector Table (AIVT) is located after the IVT, as shown in Figure 7-1. Access to the AIVT is provided by the ALTIVT control bit (INTCON2<15>). If the ALTIVT bit is set, all interrupt and exception processes use the alternate vectors instead of the default vectors. The alternate vectors are organized in the same manner as the default vectors. The AIVT supports debugging by providing a means to switch between an application and a support environment without requiring the interrupt vectors to be reprogrammed. This feature also enables switching between applications for evaluation of different software algorithms at run time. If the AIVT is not needed, the AIVT should be programmed with the same addresses used in the IVT. 7.2 Reset Sequence A device Reset is not a true exception because the interrupt controller is not involved in the Reset process. The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/ X04 device clears its registers in response to a Reset, which forces the PC to zero. The digital signal controller then begins program execution at location 0x000000. A GOTO instruction at the Reset address can redirect program execution to the appropriate start-up routine.

INTCON1 contains the Interrupt Nesting Disable (NSTDIS) bit as well as the control and status flags for the processor trap sources. The INTCON2 register controls the external interrupt request signal behavior and the use of the Alternate Interrupt Vector Table. 7.3.2 IFSx The IFSx registers maintain all of the interrupt request flags. Each source of interrupt has a status bit, which is set by the respective peripherals or external signal and is cleared via software. 7.3.3 IECx The IECx registers maintain all of the interrupt enable bits. These control bits are used to individually enable interrupts from the peripherals or external signals. 7.3.4 7.3.5 INTTREG The INTTREG register contains the associated interrupt vector number and the new CPU Interrupt priority Level, which are latched into the Vector Number (VECNUM<6:0>) and Interrupt Level (ILR<3:0>) bit fields in the INTTREG register. The new Interrupt Priority Level is the priority of the pending interrupt. The interrupt sources are assigned to the IFSx, IECx and IPCx registers in the same sequence that they are listed in Table 7-1. For example, the INT0 (External Interrupt 0) is shown as having vector number 8 and a natural order priority of 0. Thus, the INT0IF bit is found in IFS0<0>, the INT0IE bit is found in IEC0<0> and the INT0IP bits are found in the first position of IPC0 (IPC0<2:0>). 7.3.6 STATUS/CONTROL REGISTERS Although they are not specifically part of the interrupt control hardware, two of the CPU Control registers contain bits that control interrupt functionality. * The CPU STATUS register, SR, contains the IPL<2:0> bits (SR<7:5>). These bits indicate the current CPU interrupt Priority Level. The user can change the current CPU priority level by writing to the IPL bits. * The CORCON register contains the IPL3 bit, which together with IPL<2:0>, indicates the current CPU priority level. IPL3 is a read-only bit so that trap events cannot be masked by the user software. All Interrupt registers are described in Register 7-1 through Register 7-35 in the following pages. IPCx The IPCx registers are used to set the Interrupt Priority Level for each source of interrupt. Each user interrupt source can be assigned to one of eight priority levels.

Set the NSTDIS bit (INTCON1<15>) if nested interrupts are not desired. Select the user-assigned priority level for the interrupt source by writing the control bits in the appropriate IPCx register. The priority level will depend on the specific application and type of interrupt source. If multiple priority levels are not desired, the IPCx register control bits for all enabled interrupt sources can be programmed to the same non-zero value. Note: 3. 4. At a device Reset, the IPCx registers are initialized such that all user interrupt sources are assigned to priority level 4. Clear the interrupt flag status bit associated with the peripheral in the associated IFSx register. Enable the interrupt source by setting the interrupt enable control bit associated with the source in the appropriate IECx register. 7.4.2 TRAP SERVICE ROUTINE A Trap Service Routine (TSR) is coded like an ISR, except that the appropriate trap status flag in the INTCON1 register must be cleared to avoid re-entry into the TSR. 7.4.4 INTERRUPT DISABLE The following steps outline the procedure to disable all user interrupts: 1. 2. Push the current SR value onto the software stack using the PUSH instruction. Force the CPU to priority level 7 by inclusive ORing the value 0xE0 with SRL. To enable user interrupts, the POP instruction can be used to restore the previous SR value. Note: Only user interrupts with a priority level of 7 or lower can be disabled. Trap sources (level 8-level 15) cannot be disabled. The DISI instruction provides a convenient way to disable interrupts of priority levels 1-6 for a fixed period of time. Level 7 interrupt sources are not disabled by the DISI instruction. INTERRUPT SERVICE ROUTINE The method used to declare an ISR and initialize IVT with the correct vector address depends on programming language (C or assembler) and language development toolsuite used to develop application. the the the the In general, the user application must clear the interrupt flag in the appropriate IFSx register for the source of interrupt that the ISR handles. Otherwise, program will re-enter the ISR immediately after exiting the routine. If the ISR is coded in assembly language, it must be terminated using a RETFIE instruction to unstack the saved PC value, SRL value and old CPU priority level.

User software can tune the FRC frequency. User software can optionally specify a factor (ranging from 1:2 to 1:256) by which the FRC clock frequency is divided. This factor is selected using the FRCDIV<2:0> (CLKDIV<10:8>) bits. The primary oscillator can use one of the following as its clock source: SYSTEM CLOCK SELECTION The oscillator source used at a device Power-on Reset event is selected using Configuration bit settings. The oscillator Configuration bit settings are located in the Configuration registers in the program memory. (Refer to Section 21.1 "Configuration Bits" for further details.) The Initial Oscillator Selection Configuration bits, FNOSC<2:0> (FOSCSEL<2:0>), and the Primary Oscillator Mode Select Configuration bits, POSCMD<1:0> (FOSC<1:0>), select the oscillator source that is used at a Power-on Reset. The FRC primary oscillator is the default (unprogrammed) selection. The Configuration bits allow users to choose among 12 different clock modes, shown in Table 8-1. * XT (Crystal): Crystals and ceramic resonators in the range of 3 MHz to 10 MHz. The crystal is connected to the OSC1 and OSC2 pins. * HS (High-Speed Crystal): Crystals in the range of 10 MHz to 40 MHz. The crystal is connected to the OSC1 and OSC2 pins. * EC (External Clock): The external clock signal is directly applied to the OSC1 pin. The LPRC internal oscIllator runs at a nominal frequency of 32.768 kHz. It is also used as a reference clock by the Watchdog Timer (WDT) and Fail-Safe Clock Monitor (FSCM). The clock signals generated by the FRC and primary oscillators can be optionally applied to an on-chip Phase-Locked Loop (PLL) to provide a wide range of TABLE 8-1: output frequencies for device operation. PLL configuration is described in Section 8.1.3 "PLL Configuration". The output of the oscillator (or the output of the PLL if a PLL mode has been selected), FOSC, is divided by 2 to generate the device instruction clock (FCY) and the peripheral clock time base (FP). FCY defines the operating speed of the device and speeds up to 40 MHz are supported by the dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 architecture. Instruction execution speed or device operating frequency, FCY, is given by Equation 8-1.

The PLL provides significant flexibility in selecting the device operating speed. A block diagram of the PLL is shown in Figure 8-2. The output of the primary oscillator or FRC, denoted as `FIN', is divided down by a prescale factor (N1) of 2, 3, ... or 33 before being provided to the PLL's Voltage Controlled Oscillator (VCO). The input to the VCO must be selected in the range of 0.8 MHz to 8 MHz. The prescale factor `N1' is selected using the PLLPRE<4:0> bits (CLKDIV<4:0>). The PLL Feedback Divisor, selected using the PLLDIV<8:0> bits (PLLFBD<8:0>), provides a factor, `M', by which the input to the VCO is multiplied. This factor must be selected such that the resulting VCO output frequency is in the range of 100 MHz to 200 MHz. The VCO output is further divided by a postscale factor, `N2'. This factor is selected using the PLLPOST<1:0> bits (CLKDIV<7:6>). `N2' can be either 2, 4, or 8, and must be selected such that the PLL output frequency (FOSC) is in the range of 12.5 MHz to 80 MHz, which generates device operating speeds of 6.25-40 MIPS. FIGURE 8-2: For a primary oscillator or FRC oscillator, output `FIN', the PLL output `FOSC' is given by Equation 8-2. EQUATION 8-2: FOSC CALCULATION FOSC = FIN * M ( N1*N2 ) For example, suppose a 10 MHz crystal is being used with the selected oscillator mode of XT with PLL (see Equation 8-3). * If PLLPRE<4:0> = 0, then N1 = 2. This yields a VCO input of 10/2 = 5 MHz, which is within the acceptable range of 0.8-8 MHz. * If PLLDIV<8:0> = 0x1E, then M = 32. This yields a VCO output of 5 x 32 = 160 MHz, which is within the 100-200 MHz ranged needed. * If PLLPOST<1:0> = 0, then N2 = 2. This provides a Fosc of 160/2 = 80 MHz. The resultant device operating speed is 80/2 = 40 MIPS.

DS70318F-page 135 dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 8.2 Auxiliary Clock Generation The auxiliary clock generation is used for a peripherals that need to operate at a frequency unrelated to the system clock such as a PWM or ADC. The primary oscillator and internal FRC oscillator sources can be used with an auxiliary PLL to obtain the auxiliary clock. The auxiliary PLL has a fixed 16x multiplication factor. The auxiliary clock has the following configuration restrictions: * For proper PWM operation, auxiliary clock generation must be configured for 120 MHz (see parameter OS56 in Table 24-18 in Section 24.0 "Electrical Characteristics"). If a slower frequency is desired, the PWM Input Clock Prescaler (Divider) Select bits (PCLKDIV<2:0>) should be used. * To achieve 1.04 ns PWM resolution, the auxiliary clock must use the 16x auxiliary PLL (APLL). All other clock sources will have a minimum PWM resolution of 8 ns. * If the primary PLL is used as a source for the auxiliary clock, the primary PLL should be configured up to a maximum operation of 30 MIPS or less 8.3 Reference Clock Generation The reference clock output logic provides the user with the ability to output a clock signal based on the system clock or the crystal oscillator on a device pin. The user application can specify a wide range of clock scaling prior to outputting the reference clock.

DS70318F-page 143 dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 8.5 Clock Switching Operation Users can switch applications among any of the four clock sources (primary, LP, FRC and LPRC) under software control at any time. To limit the possible side effects of this flexibility, dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 devices have a safeguard lock built into the switch process. Note: 8.5.1 Primary oscillator mode has three different submodes (XT, HS and EC), which are determined by the POSCMD<1:0> Configuration bits. While an application can switch to and from primary oscillator mode in software, it cannot switch among the different primary submodes without reprogramming the device. ENABLING CLOCK SWITCHING To enable clock switching, the FCKSM1 Configuration bit in the Configuration register must be programmed to `0'. (Refer to Section 21.1 "Configuration Bits" for further details.) If the FCKSM1 Configuration bit is unprogrammed (`1'), the clock switching function and Fail-Safe Clock Monitor function are disabled. This is the default setting. 2. If a valid clock switch has been initiated, the LOCK (OSCCON<5>) and the CF (OSCCON<3>) status bits are cleared. The new oscillator is turned on by the hardware if it is not currently running. If a crystal oscillator must be turned on, the hardware waits until the Oscillator Start-up Timer (OST) expires. If the new source is using the PLL, the hardware waits until a PLL lock is detected (LOCK = 1). The hardware waits for 10 clock cycles from the new clock source and then performs the clock switch. The hardware clears the OSWEN bit to indicate a successful clock transition. In addition, the NOSC<2:0> bit values are transferred to the COSC<2:0> status bits. The old clock source is turned off at this time, with the exception of LPRC (if WDT or FSCM are enabled). 3. 4. 5. 6. Note 1: The processor continues to execute code throughout the clock switching sequence. Timing-sensitive code should not be executed during this time. 2: Direct clock switches between any primary oscillator mode with PLL and FRCPLL mode are not permitted. This applies to clock switches in either direction. In these instances, the application must switch to FRC mode as a transition clock source between the two PLL modes. 3: Refer to Section 42. "Oscillator (Part IV)" (DS70307) in the "dsPIC33F/PIC24H Family Reference Manual" for details. The NOSC<2:0> control bits (OSCCON<10:8>) do not control the clock selection when clock switching is disabled. However, the COSC<2:0> bits (OSCCON<14:12>) reflect the clock source selected by the FNOSC Configuration bits. The OSWEN control bit (OSCCON<0>) has no effect when clock switching is disabled. It is held at `0' at all times. 8.5.2 OSCILLATOR SWITCHING SEQUENCE To perform a clock switch, the following basic sequence is required: 1. 2. 3. 4. 5. If required, read the COSC<2:0> bits to determine the current oscillator source. Perform the unlock sequence to allow a write to the OSCCON register high byte. Write the appropriate value to the NOSC<2:0> control bits for the new oscillator source. Perform the unlock sequence to allow a write to the OSCCON register low byte. Set the OSWEN bit to initiate the oscillator switch. After the basic sequence is completed, the system clock hardware responds as follows: 1. The clock switching hardware compares the COSC<2:0> status bits with the new value of the NOSC<2:0> control bits. If they are the same, the clock switch is a redundant operation. In this case, the OSWEN bit is cleared automatically and the clock switch is aborted. DS70318F-page 144 8.6 Fail-Safe Clock Monitor (FSCM) The Fail-Safe Clock Monitor (FSCM) allows the device to continue to operate even in the event of an oscillator failure. The FSCM function is enabled by programming. If the FSCM function is enabled, the LPRC internal oscillator runs at all times (except during Sleep mode) and is not subject to control by the Watchdog Timer. During an oscillator failure, the FSCM generates a clock failure trap event and switches the system clock over to the FRC oscillator. Then, the application program can either attempt to restart the oscillator or execute a controlled shutdown. The trap can be treated as a warm Reset by simply loading the Reset address into the oscillator fail trap vector. If the PLL multiplier is used to scale the system clock, the internal FRC is also multiplied by the same factor on clock failure. Essentially, the device switches to FRC with PLL on a clock failure.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 9. "Watchdog Timer and Power-Saving Modes" (DS70196) in the "dsPIC33F/PIC24H Family Reference Manual", which is available from the Microchip web site (www.microchip.com). 2: Some registers and associated bits described in this section may not be available on all devices. Refer to Section 4.0 "Memory Organization" in this data sheet for device-specific register and bit information. 9.2 Instruction-Based Power-Saving Modes The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/ X04 devices have two special power-saving modes that are entered through the execution of a special PWRSAV instruction. Sleep mode stops clock operation and halts all code execution. Idle mode halts the CPU and code execution, but allows peripheral modules to continue operation. The assembler syntax of the PWRSAV instruction is shown in Example 9-1. Note: SLEEP_MODE and IDLE_MODE are constants defined in the assembler include file for the selected device. Sleep and Idle modes can be exited as a result of an enabled interrupt, WDT time-out or a device Reset. When the device exits these modes, it is said to wake-up. 9.2.1 SLEEP MODE The following occur in Sleep mode: The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/ X04 devices provide the ability to manage power consumption by selectively managing clocking to the CPU and the peripherals. In general, a lower clock frequency and a reduction in the number of circuits being clocked constitutes lower consumed power. dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 devices can manage power consumption in four different ways: * * * * Clock Frequency Instruction-Based Sleep and Idle modes Software-Controlled Doze mode Selective Peripheral Control in Software Combinations of these methods can be used to selectively tailor an application's power consumption while still maintaining critical application features, such as timing-sensitive communications. 9.1 Clock Frequency and Clock Switching The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 devices allow a wide range of clock frequencies to be selected under application control. If the system clock configuration is not locked, users can choose low-power or high-precision oscillators by simply changing the NOSC<2:0> bits (OSCCON<10:8>). The process of changing a system clock during operation, as well as limitations to the process, are discussed in more detail in Section 8.0 "Oscillator Configuration". EXAMPLE 9-1: * The system clock source is shut down. If an on-chip oscillator is used, it is turned off * The device current consumption is reduced to a minimum, provided that no I/O pin is sourcing current * The Fail-Safe Clock Monitor does not operate, since the system clock source is disabled * The LPRC clock continues to run in Sleep mode if the WDT is enabled * The WDT, if enabled, is automatically cleared prior to entering Sleep mode * Some device features or peripherals may continue to operate. This includes the items such as the input change notification on the I/O ports or peripherals that use an external clock input. * Any peripheral that requires the system clock source for its operation is disabled The device will wake-up from Sleep mode on any of these events: * Any interrupt source that is individually enabled * Any form of device Reset * A WDT time-out On wake-up from Sleep mode, the processor restarts with the same clock source that was active when Sleep mode was entered. PWRSAV INSTRUCTION SYNTAX PWRSAV #SLEEP_MODE PWRSAV #IDLE_MODE ; Put the device into SLEEP mode ; Put the device into IDLE mode (c) 2008-2012 Microchip Technology Inc. DS70318F-page 145 dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 9.2.2 IDLE MODE The following occur in Idle mode: * The CPU stops executing instructions * The WDT is automatically cleared * The system clock source remains active. By default, all peripheral modules continue to operate normally from the system clock source, but can also be selectively disabled (see Section 9.4 "Peripheral Module Disable"). * If the WDT or FSCM is enabled, the LPRC also remains active The device will wake-up from Idle mode on any of these events: * Any interrupt that is individually enabled * Any device Reset * A WDT time-out On wake-up from Idle mode, the clock is reapplied to the CPU and instruction execution will begin (2-4 clock cycles later), starting with the instruction following the PWRSAV instruction, or the first instruction in the ISR. 9.2.3 INTERRUPTS COINCIDENT WITH POWER SAVE INSTRUCTIONS Any interrupt that coincides with the execution of a PWRSAV instruction is held off until entry into Sleep or Idle mode has completed. The device then wakes up from Sleep or Idle mode. 9.3 Doze Mode The preferred strategies for reducing power consumption are changing clock speed and invoking one of the power-saving modes. In some circumstances, this may not be practical. For example, it may be necessary for an application to maintain uninterrupted synchronous communication, even while it is doing nothing else. Reducing system clock speed can introduce communication errors, while using a power-saving mode can stop communications completely. Doze mode is a simple and effective alternative method to reduce power consumption while the device is still executing code. In this mode, the system clock continues to operate from the same source and at the same speed. Peripheral modules continue to be clocked at the same speed, while the CPU clock speed is reduced. Synchronization between the two clock domains is maintained, allowing the peripherals to access the SFRs while the CPU executes code at a slower rate. DS70318F-page 146 Doze mode is enabled by setting the DOZEN bit (CLKDIV<11>). The ratio between peripheral and core clock speed is determined by the DOZE<2:0> bits (CLKDIV<14:12>). There are eight possible configurations, from 1:1 to 1:128, with 1:1 being the default setting. Programs can use Doze mode to selectively reduce power consumption in event-driven applications. This allows clock-sensitive functions, such as synchronous communications, to continue without interruption while the CPU idles, waiting for something to invoke an interrupt routine. An automatic return to full-speed CPU operation on interrupts can be enabled by setting the ROI bit (CLKDIV<15>). By default, interrupt events have no effect on Doze mode operation. For example, suppose the device is operating at 20 MIPS and the CAN module has been configured for 500 kbps based on this device operating speed. If the device is placed in Doze mode with a clock frequency ratio of 1:4, the CAN module continues to communicate at the required bit rate of 500 kbps, but the CPU now starts executing instructions at a frequency of 5 MIPS. 9.4 Peripheral Module Disable The Peripheral Module Disable (PMD) registers provide a method to disable a peripheral module by stopping all clock sources supplied to that module. When a peripheral is disabled using the appropriate PMD control bit, the peripheral is in a minimum power consumption state. The control and status registers associated with the peripheral are also disabled, so writes to those registers will have no effect and read values will be invalid. A peripheral module is enabled only if both the associated bit in the PMD register is cleared and the peripheral is supported by the specific dsPIC(R) DSC variant. If the peripheral is present in the device, it is enabled in the PMD register by default. Note: If a PMD bit is set, the corresponding module is disabled after a delay of one instruction cycle. Similarly, if a PMD bit is cleared, the corresponding module is enabled after a delay of one instruction cycle (assuming the module control registers are already configured to enable module operation).

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 10. "I/O Ports" (DS70193) in the "dsPIC33F/PIC24H Family Reference Manual", which is available on Microchip web site (www.microchip.com). 2: Some registers and associated bits described in this section may not be available on all devices. Refer to Section 4.0 "Memory Organization" in this data sheet for device-specific register and bit information. All of the device pins (except VDD, VSS, MCLR and OSC1/CLKI) are shared among the peripherals and the parallel I/O ports. All I/O input ports feature Schmitt Trigger inputs for improved noise immunity. 10.1 Parallel I/O (PIO) Ports Generally a parallel I/O port that shares a pin with a peripheral is 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 FIGURE 10-1: has ownership of the output data and control signals of the I/O pin. The logic also prevents "loop through", in which a port's digital output can drive the input of a peripheral that shares the same pin. Figure 10-1 shows how ports are shared with other peripherals and the associated I/O pin to which they are connected. 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 their operation as digital I/O. The data direction register (TRISx) determines whether the pin is an input or an output. If the data direction bit is `1', then 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. Reads from the port (PORTx) read the port pins, while writes to the port pins write the latch. Any bit and its associated data and control registers that are not valid for a particular device will be disabled. That means the corresponding LATx and TRISx registers and the port pin will read as zeros. When a pin is shared with another peripheral or function that is defined as an input only, it is nevertheless regarded as a dedicated port because there is no other competing source of outputs.

DS70318F-page 153 dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 10.2 Open-Drain Configuration In addition to the PORT, LAT and TRIS registers for data control, some digital-only port pins can also be individually configured for either digital or open-drain output. This is controlled by the Open-Drain Control register, ODCx, associated with each port. Setting any of the bits configures the corresponding pin to act as an open-drain output. The open-drain feature allows the generation of outputs higher than VDD (for example, 5V) on any desired 5V tolerant pins by using external pull-up resistors. The maximum open-drain voltage allowed is the same as the maximum VIH specification. Refer to "Pin Diagrams" for the available pins and their functionality. 10.3 Configuring Analog Port Pins The ADPCFG and TRIS registers control the operation of the Analog-to-Digital (A/D) port pins. The port pins that are to function as analog inputs must have their corresponding TRIS bit set (input). If the TRIS bit is cleared (output), the digital output level (VOH or VOL) will be converted. The ADPCFG register has a default value of 0x0000; therefore, all pins that share ANx functions are analog (not digital) by default. When the PORT register is read, all pins configured as analog input channels will read as cleared (a low level). Pins configured as digital inputs will not convert an analog input. Analog levels on any pin defined as a digital input (including the ANx pins) can cause the input buffer to consume current that exceeds the device specifications. EQUATION 10-1: MOV MOV NOP BTSS 0xFF00, W0 W0, TRISBB PORTB, #13 DS70318F-page 154 10.4 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. An example is shown in Example 10-1. 10.5 Input Change Notification The input change notification function of the I/O ports allows the dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 devices to generate interrupt requests to the processor in response to a Change-Of-State (COS) on selected input pins. This feature can detect input Change-Of-States even in Sleep mode, when the clocks are disabled. Depending on the device pin count, up to 30 external signals (CNx pin) can be selected (enabled) for generating an interrupt request on a Change-Of-State. Four control registers are associated with the CN module. The CNEN1 and CNEN2 registers contain the interrupt enable control bits for each of the CN input pins. Setting any of these bits enables a CN interrupt for the corresponding pins. Each CN pin also has a weak pull-up connected to it. The pull-ups act as a current source connected to the pin, and eliminate the need for external resistors when the push button or keypad devices are connected. The pull-ups are enabled separately using the CNPU1 and CNPU2 registers, which contain the control bits for each of the CN pins. Setting any of the control bits enables the weak pull-ups for the corresponding pins. Note: Pull-ups on change notification pins should always be disabled when the port pin is configured as a digital output.

By increasing the pinout options available on a particular device, programmers can better tailor the microcontroller to their entire application, rather than trimming the application to fit the device. The peripheral pin select configuration feature operates over a fixed subset of digital I/O pins. Programmers can independently map the input and/or output of most digital peripherals to any one of these I/O pins. Peripheral pin select is performed in software, and generally does not require the device to be reprogrammed. Hardware safeguards are included that prevent accidental or spurious changes to the peripheral mapping, once it has been established. 10.6.1 AVAILABLE PINS The peripheral pin select feature is used with a range of up to 30 pins. The number of available pins depends on the particular device and its pin count. Pins that support the peripheral pin select feature include the designation "RPn" in their full pin designation, where "RP" designates a remappable peripheral and "n" is the remappable pin number. 10.6.2 10.6.2.1 The inputs of the peripheral pin select options are mapped on the basis of the peripheral. A control register associated with a peripheral dictates the pin it will be mapped to. The RPINRx registers are used to configure peripheral input mapping (see Register 10-1 through Register 10-14). Each register contains sets of 6-bit fields, with each set associated with one of the remappable peripherals. Programming a given peripheral's bit field with an appropriate 6-bit value maps the RPn pin with that value to that peripheral. For any given device, the valid range of values for any bit field corresponds to the maximum number of peripheral pin selections supported by the device. Figure 10-2 Illustrates remappable pin selection for U1RX input. Note: The association of a peripheral to a peripheral selectable pin is handled in two different ways, depending on whether an input or output is being mapped. For input mapping only, the Peripheral Pin Select (PPS) functionality does not have priority over the TRISx settings. Therefore, when configuring the RPx pin for input, the corresponding bit in the TRISx register must also be configured for input (i.e., set to `1'). FIGURE 10-2: CONTROLLING PERIPHERAL PIN SELECT Peripheral pin select features are controlled through two sets of Special Function Registers: one to map peripheral inputs and another one to map outputs. Because they are separately controlled, a particular peripheral's input and output (if the peripheral has both) can be placed on any selectable function pin without constraint.

In this case, a control register associated with a particular pin dictates the peripheral output to be mapped. The RPORx registers are used to control output mapping. Like the RPINRx registers, each register contains sets of 6-bit fields, with each set associated with one RPn pin (see Register 10-15 through Register 10-31). The value of the bit field corresponds to one of the peripherals, and that peripheral's output is mapped to the pin (see Table 10-2 and Figure 10-3). The list of peripherals for output mapping also includes a null value of `00000' because of the mapping technique. This permits any given pin to remain unconnected from the output of any of the pin selectable peripherals.

DS70318F-page 157 dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 10.6.2.3 Virtual Pins dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 devices support four virtual RPn pins (RP32, RP33, RP34 and RP35), which are identical in functionality to all other RPn pins, with the exception of pinouts. These four pins are internal to the devices and are not connected to a physical device pin. These pins provide a simple way for inter-peripheral connection without utilizing a physical pin. For example, the output of the analog comparator can be connected to RP32 and the PWM Fault input can be configured for RP32 as well. This configuration allows the analog comparator to trigger PWM Faults without the use of an actual physical pin on the device. 10.6.3 CONTROLLING CONFIGURATION CHANGES Because peripheral remapping can be changed during run time, some restrictions on peripheral remapping are needed to prevent accidental configuration changes. dsPIC33F devices include three features to prevent alterations to the peripheral map: * Control register lock sequence * Continuous state monitoring * Configuration bit pin select lock 10.6.3.1 Control Register Lock Under normal operation, writes to the RPINRx and RPORx registers are not allowed. Attempted writes appear to execute normally, but the contents of the registers remain unchanged. To change these registers, they must be unlocked in hardware. The register lock is controlled by the IOLOCK bit (OSCCON<6>). Setting IOLOCK prevents writes to the control registers; clearing IOLOCK allows writes. Unlike the similar sequence with the oscillator's LOCK bit, IOLOCK remains in one state until changed. This allows all of the peripheral pin selects to be configured with a single unlock sequence followed by an update to all control registers, then locked with a second lock sequence. 10.6.3.2 Continuous State Monitoring In addition to being protected from direct writes, the contents of the RPINRx and RPORx registers are constantly monitored in hardware by shadow registers. If an unexpected change in any of the registers occurs (such as cell disturbances caused by ESD or other external events), a Configuration Mismatch Reset will be triggered. 10.6.3.3 Configuration Bit Pin Select Lock As an additional level of safety, the device can be configured to prevent many write session to the RPINRx and RPORx registers. The IOL1WAY (FOSC<5>) Configuration bit blocks the IOLOCK bit from being cleared after it has been set once. If IOLOCK remains set, the register unlock procedure will not execute and the Peripheral Pin Select Control registers cannot be written to. The only way to clear the bit and re-enable peripheral remapping is to perform a device Reset. In the default (unprogrammed) state, IOL1WAY is set, restricting users to one write session. Programming IOL1WAY allows user applications unlimited access (with the proper use of the unlock sequence) to the Peripheral Pin Select registers. To set or clear IOLOCK, a specific command sequence must be executed: 1. 2. 3. Write 0x46 to OSCCON<7:0>. Write 0x57 to OSCCON<7:0>. Clear (or set) IOLOCK as a single operation. Note: MPLAB(R) C30 provides built-in C language functions for unlocking the OSCCON register: __builtin_write_OSCCONL(value) __builtin_write_OSCCONH(value) See the MPLAB C30 Help files for more information.

In Synchronous Counter mode, the input clock is derived from the external clock input at the TxCK pin. The timer modes are determined by the following bits: * TCS (TxCON<1>): Timer Clock Source Control bit * TGATE (TxCON<6>): Timer Gate Control bit When configured for 32-bit operation, only the Type B Timer Control (TxCON) register bits are required for setup and control while the Type C Timer Control register bits are ignored (except the TSIDL bit). For interrupt control, the combined 32-bit timer uses the interrupt enable, interrupt flag and interrupt priority control bits of the Type C timer. The interrupt control and status bits for the Type B timer are ignored during 32-bit timer operation. The Timer2 and Timer 3 that can be combined to form a 32-bit timer are listed in Table 12-2.

Select the timer prescaler ratio using the TCKPS<1:0> bits. Set the Clock and Gating modes using the TCS and TGATE bits. Load the timer period value into the PRx register. If interrupts are required, set the interrupt enable bit, TxIE. Use the priority bits, TxIP<2:0>, to set the interrupt priority. Set the TON bit. 32-BIT TIMER 4. 5. 6. Set the T32 control bit. Select the prescaler ratio for Timer2 using the TCKPS<1:0> bits. Set the Clock and Gating modes using the corresponding TCS and TGATE bits. Load the timer period value. PR3 contains the most significant word of the value, while PR2 contains the least significant word. If interrupts are required, set the interrupt enable bit, T3IE. Use the priority bits, T3IP<2:0>, to set the interrupt priority. While Timer2 controls the timer, the interrupt appears as a Timer3 interrupt. Set the corresponding TON bit. The timer value at any point is stored in the register pair, TMR3:TMR2, which always contains the most significant word of the count, while TMR2 contains the least significant word.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 43. "High- Speed PWM" (DS70323) in the "dsPIC33F/ PIC24H Family Reference Manual", which is available on the Microchip web site (www.microchip.com). 2: Some registers and associated bits described in this section may not be available on all devices. Refer to Section 4.0 "Memory Organization" in this data sheet for device-specific register and bit information. The high-speed PWM module on the dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/ X04 devices supports a wide variety of PWM modes and output formats. This PWM module is ideal for power conversion applications, such as: * * * * * * * AC/DC Converters DC/DC Converters Power Factor Correction (PFC) Uninterruptible Power Supply (UPS) Inverters Battery Chargers Digital Lighting 15.1 Features Overview The high-speed PWM module incorporates the following features: * 2-4 PWM generators with 4-8 outputs * Individual time base and duty cycle for each of the eight PWM outputs * Dead time for rising and falling edges: * Duty cycle resolution of 1.04 ns * Dead-time resolution of 1.04 ns * Phase shift resolution of 1.04 ns (c) 2008-2012 Microchip Technology Inc. * Frequency resolution of 1.04 ns * PWM modes supported: - Standard Edge-Aligned - True Independent Output - Complementary - Center-Aligned - Push-Pull - Multiphase - Variable Phase - Fixed Off-Time - Current Reset - Current-Limit * Independent Fault/Current-Limit inputs for each of the eight PWM outputs * Output override control * Special Event Trigger * PWM capture feature * Prescaler for input clock * Dual trigger from PWM to ADC * PWMxH, PWMxL output pin swapping * PWM4H, PWM4L pins remappable * On-the-fly PWM frequency, duty cycle and phase shift changes * Disabling of Individual PWM generators to reduce power consumption * Leading-Edge Blanking (LEB) functionality Note: Duty cycle, dead-time, phase shift and frequency resolution is 8.32 ns in Center-Aligned PWM mode. Figure 15-1 conceptualizes the PWM module in a simplified block diagram. Figure 15-2 illustrates how the module hardware is partitioned for each PWM output pair for the Complementary PWM mode. Each functional unit of the PWM module is discussed in subsequent sections. The PWM module contains four PWM generators. The module has up to eight PWM output pins: PWM1H, PWM1L, PWM2H, PWM2L, PWM3H, PWM3L, PWM4H and PWM4L. For complementary outputs, these eight I/O pins are grouped into H/L pairs. DS70318F-page 195 dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 15.2 Feature Description The PWM module is designed for applications that require: * High-resolution at high PWM frequencies * The ability to drive Standard, Edge-Aligned, Center-Aligned Complementary mode, and Push-Pull mode outputs * The ability to create multiphase PWM outputs For Center-Aligned mode, the duty cycle, period phase and dead-time resolutions will be 8.32 ns. Two common, medium power converter topologies are push-pull and half-bridge. These designs require the PWM output signal to be switched between alternate pins, as provided by the Push-Pull PWM mode. Phase-shifted PWM describes the situation where each PWM generator provides outputs, but the phase relationship between the generator outputs is specifiable and changeable. Multiphase PWM is often used to improve DC/DC converter load transient response, and reduce the size of output filter capacitors and inductors. Multiple DC/ DC converters are often operated in parallel, but phase-shifted in time. A single PWM output operating at 250 kHz has a period of 4 s, but an array of four PWM channels, staggered by 1 s each, yields an effective switching frequency of 1 MHz. Multiphase PWM applications typically use a fixed-phase relationship. Variable phase PWM is useful in Zero Voltage Transition (ZVT) power converters. Here, the PWM duty cycle is always 50%, and the power flow is controlled by varying the relative phase shift between the two PWM generators.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 18. "Serial Peripheral Interface (SPI)" (DS70206) in the "dsPIC33F/PIC24H Family Reference Manual", which is available on the Microchip web site (www.microchip.com). 2: Some registers and associated bits described in this section may not be available on all devices. Refer to Section 4.0 "Memory Organization" in this data sheet for device-specific register and bit information. FIGURE 16-1: The Serial Peripheral Interface (SPI) module is a synchronous serial interface useful for communicating with other peripheral or microcontroller devices. These peripheral devices can be serial EEPROMs, shift registers, display drivers, analog-to-digital converters and so on. The SPI module is compatible with SPI and SIOP from Motorola(R). The SPI module consists of a 16-bit shift register, SPIxSR (where x = 1), used for shifting data in and out, and a buffer register, SPIxBUF. A control register, SPIxCON, configures the module. Additionally, a status register, SPIxSTAT, indicates status conditions. The serial interface consists of the following four pins: * * * * SDIx (Serial Data Input) SDOx (Serial Data Output) SCKx (Shift Clock Input Or Output) SSx (Active-Low Slave Select). In Master mode operation, SCK is a clock output; in Slave mode, it is a clock input.

Refer to Section 4.0 "Memory Organization" in this data sheet for device-specific register and bit information. (I2C) The Inter-Integrated Circuit module provides complete hardware support for both Slave and Multi-Master modes of the I2C serial communication standard with a 16-bit interface. The I2C module has a 2-pin interface, where: * The SCLx pin is clock * The SDAx pin is data The I2C module offers the following key features: * I2C interface supporting both Master and Slave modes of operation * I2C Slave mode supports 7-bit and 10-bit addressing * I2C Master mode supports 7-bit and 10-bit addressing * I2C port allows bidirectional transfers between master and slaves * Serial clock synchronization for I2C port can be used as a handshake mechanism to suspend and resume serial transfer (SCLREL control) * I2C supports multi-master operation, detects bus collision and arbitrates accordingly 17.1 Operating Modes The hardware fully implements all the master and slave functions of the I2C Standard and Fast mode specifications, as well as 7-bit and 10-bit addressing. The I2C module can operate either as a slave or a master on an I2C bus. The following types of I2C operation are supported: * * * (c) 2008-2012 Microchip Technology Inc.

The I2CxCON register is readable and writable. The lower six bits of I2CxSTAT are read-only. The remaining bits of the I2CxSTAT are read/write: * I2CxRSR is the shift register used for shifting data internal to the module and the user application has no access to it * I2CxRCV is the receive buffer and the register to which data bytes are written, or from which data bytes are read * I2CxTRN is the transmit register to which bytes are written during a transmit operation * The I2CxADD register holds the slave address * A status bit, ADD10, indicates 10-bit Address mode * The I2CxBRG acts as the Baud Rate Generator (BRG) reload value In receive operations, I2CxRSR and I2CxRCV together form a double-buffered receiver. When I2CxRSR receives a complete byte, it is transferred to I2CxRCV, and an interrupt pulse is generated. (c) 2008-2012 Microchip Technology Inc.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 44. "High-Speed 10-bit Analog-to-Digital Converter (ADC)" (DS70321) in the "dsPIC33F/PIC24H Family Reference Manual", which is available on the Microchip web site (www.microchip.com). 2: Some registers and associated bits described in this section may not be available on all devices. Refer to Section 4.0 "Memory Organization" in this data sheet for device-specific register and bit information. The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 devices provide high-speed successive approximation analog to digital conversions to support applications such as AC/DC and DC/DC power converters. 19.1 Features Overview The ADC module comprises the following features: * 10-bit resolution * Unipolar inputs * Up to two Successive Approximation Registers (SARs) * Up to 12 external input channels * Up to two internal analog inputs * Dedicated result register for each analog input * 1 LSB accuracy at 3.3V * Single supply operation * 4 Msps conversion rate at 3.3V (devices with two SARs) * 2 Msps conversion rate at 3.3V (devices with one SAR) * Low-power CMOS technology 19.2 Module Description This ADC module is designed for applications that require low latency between the request for conversion and the resultant output data. Typical applications include: * AC/DC power supplies * DC/DC converters * Power Factor Correction (PFC) (c) 2008-2012 Microchip Technology Inc. This ADC works with the high-speed PWM module in power control applications that require high-frequency control loops. This module can sample and convert two analog inputs in a 0.5 microsecond when two SARs are used. This small conversion delay reduces the "phase lag" between measurement and control system response. Up to five inputs may be sampled at a time (four inputs from the dedicated sample and hold circuits and one from the shared sample and hold circuit). If multiple inputs request conversion, the ADC will convert them in a sequential manner, starting with the lowest order input. This ADC design provides each pair of analog inputs (AN1,AN0), (AN3,AN2),..., the ability to specify its own trigger source out of a maximum of sixteen different trigger sources. This capability allows this ADC to sample and convert analog inputs that are associated with PWM generators operating on independent time bases. The user application typically requires synchronization between analog data sampling and PWM output to the application circuit. The very high-speed operation of this ADC module allows "data on demand". In addition, several hardware features have been added to the peripheral interface to improve real-time performance in a typical DSP-based application. * * * * Result alignment options Automated sampling External conversion start control Two internal inputs to monitor INTREF internal reference and EXTREF input signal 19.3 Module Functionality The high-speed 10-bit ADC module is designed to support power conversion applications when used with the High-Speed PWM module. The ADC may have one or two SAR modules, depending on the device variant. If two SARs are present on a device, two conversions can be processed at a time, yielding 4 Msps conversion rate. If only one SAR is present on a device, only one conversion can be processed at a time, yielding 2 Msps conversion rate. The high-speed 10-bit ADC produces two 10-bit conversion results in a 0.5 microsecond. The ADC module supports up to 12 external analog inputs and two internal analog inputs. To monitor reference voltage, two internal inputs, AN12 and AN13, are connected to the EXTREF and INTREF voltages, respectively. The analog reference voltage is defined as the device supply voltage (AVDD/AVSS). Block diagrams of the ADC module are shown in Figure 19-1 through Figure 19-6.

The ADSTAT register displays the status of the conversion processes. The ADPCFG registers configure the port pins as analog inputs or as digital I/O. The ADCPCx registers control the triggering of the ADC conversions. See Register 19-1 through Register 19-8 for detailed bit configurations. Note: A unique feature of the ADC module is its ability to sample inputs in an asynchronous manner. Individual sample and hold circuits can be triggered independently of each other.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 45. "High-Speed Analog Comparator" (DS70296) in the "dsPIC33F/PIC24H Family Reference Manual", which is available on the Microchip web site (www.microchip.com). 2: Some registers and associated bits described in this section may not be available on all devices. Refer to Section 4.0 "Memory Organization" in this data sheet for device-specific register and bit information. 20.2 Figure 20-1 shows a functional block diagram of one analog comparator from the SMPS comparator module. The analog comparator provides high-speed operation with a typical delay of 20 ns. The comparator has a typical offset voltage of 5 mV. The negative input of the comparator is always connected to the DAC circuit. The positive input of the comparator is connected to an analog multiplexer that selects the desired source pin. The dsPIC33F SMPS Comparator module monitors current and/or voltage transients that may be too fast for the CPU and ADC to capture. 20.1 Features Overview The analog comparator input pins are typically shared with pins used by the Analog-to-Digital Converter (ADC) module. Both the comparator and the ADC can use the same pins at the same time. This capability enables a user to measure an input voltage with the ADC and detect voltage transients with the comparator. The SMPS comparator module contains the following major features: * 16 selectable comparator inputs * Up to four analog comparators * 10-bit DAC for each analog comparator FIGURE 20-1: COMPARATOR MODULE BLOCK DIAGRAM INSEL<1:0> ACMPx (Trigger to PWM)(1) CMPxA(1) Status CMPxB(1) M U X (1) CMPxC CMPx(1) CMPxD 1 RANGE AVDD/2 0 Glitch Filter (1) INTREF(2) Module Description M U X CMPPOL DACOUT DAC AVSS Pulse Generator Interrupt Request 10 CMREF DACOE EXTREF(2) Note 1: 2: x = 1, 2, 3, and 4.

DS70318F-page 261 dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 20.3 Module Applications 20.5 Interaction with I/O Buffers This module provides a means for the SMPS dsPIC DSC devices to monitor voltage and currents in a power conversion application. The ability to detect transient conditions and stimulate the dsPIC DSC processor and/or peripherals, without requiring the processor and ADC to constantly monitor voltages or currents, frees the dsPIC DSC to perform other tasks. If the comparator module is enabled and a pin has been selected as the source for the comparator, then the chosen I/O pad must disable the digital input buffer associated with the pad to prevent excessive currents in the digital buffer due to analog input voltages. The comparator module has a high-speed comparator and an associated 10-bit DAC that provides a programmable reference voltage to the inverting input of the comparator. The polarity of the comparator output is user-programmable. The output of the module can be used in the following modes: The CMPCONx register (see Register 20-1) provides the control logic that configures the comparator module. The digital logic provides a glitch filter for the comparator output to mask transient signals in less than two instruction cycles. In Sleep or Idle mode, the glitch filter is bypassed to enable an asynchronous path from the comparator to the interrupt controller. This asynchronous path can be used to wake-up the processor from Sleep or Idle mode. * * * * * Generate an Interrupt Trigger an ADC Sample and Convert Process Truncate the PWM Signal (current limit) Truncate the PWM Period (current minimum) Disable the PWM Outputs (Fault latch) The output of the comparator module may be used in multiple modes at the same time, such as: 1) generate an interrupt, 2) have the ADC take a sample and convert it, and 3) truncate the PWM output in response to a voltage being detected beyond its expected value. The comparator module can also be used to wake-up the system from Sleep or Idle mode when the analog input voltage exceeds the programmed threshold voltage. 20.4 DAC The range of the DAC is controlled through an analog multiplexer that selects either AVDD/2, an internal reference source, INTREF, or an external reference source, EXTREF. The full range of the DAC (AVDD/2) will typically be used when the chosen input source pin is shared with the ADC. The reduced range option (INTREF) will likely be used when monitoring current levels using a current sense resistor. Usually, the measured voltages in such applications are small (<1.25V); therefore the option of using a reduced reference range for the comparator extends the available DAC resolution in these applications. The use of an external reference enables the user to connect to a reference that better suits their application. DACOUT, shown in Figure 20-1, can only be associated with a single comparator at a given time. Note: It should be ensured in software that multiple DACOE bits are not set. The output on the DACOUT pin will be indeterminate if multiple comparators enable the DAC output. 20.6 Digital Logic The comparator can be disabled while in Idle mode if the CMPSIDL bit is set. If a device has multiple comparators, if any CMPSIDL bit is set, then the entire group of comparators will be disabled while in Idle mode. This behavior reduces complexity in the design of the clock control logic for this module. The digital logic also provides a one TCY width pulse generator for triggering the ADC and generating interrupt requests. The CMPDACx (see Register 20-2) register provides the digital input value to the reference DAC. If the module is disabled, the DAC and comparator are disabled to reduce power consumption. 20.7 Comparator Input Range The comparator has a limitation for the input Common Mode Range (CMR) of (AVDD - 1.5V), typical. This means that both inputs should not exceed this range. As long as one of the inputs is within the Common Mode Range, the comparator output will be correct. However, any input exceeding the CMR limitation will cause the comparator input to be saturated. If both inputs exceed the CMR, the comparator output will be indeterminate. 20.8 DAC Output Range The DAC has a limitation for the maximum reference voltage input of (AVDD - 1.6) volts. An external reference voltage input should not exceed this value or the reference DAC output will become indeterminate. 20.9 Comparator Registers The comparator module is controlled by the following registers: * CMPCONx: Comparator Control Register * CMPDACx: Comparator DAC Control Register DS70318F-page 262 (c) 2008-2012 Microchip Technology Inc. dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 REGISTER 20-1: CMPCONx: COMPARATOR CONTROL REGISTER R/W-0 U-0 R/W-0 U-0 U-0 U-0 U-0 R/W-0 CMPON -- CMPSIDL -- -- -- -- DACOE bit 15 bit 8 R/W-0 R/W-0 INSEL<1:0> R/W-0 U-0 R/W-0 U-0 R/W-0 R/W-0 EXTREF -- CMPSTAT -- CMPPOL RANGE bit 7 bit 0 Legend: R = Readable bit W = Writable bit U = Unimplemented bit, read as `0' -n = Value at POR `1' = Bit is set `0' = Bit is cleared x = Bit is unknown bit 15 CMPON: Comparator Operating Mode bit 1 = Comparator module is enabled 0 = Comparator module is disabled (reduces power consumption) bit 14 Unimplemented: Read as `0' bit 13 CMPSIDL: Stop in Idle Mode bit 1 = Discontinue module operation when device enters Idle mode. 0 = Continue module operation in Idle mode If a device has multiple comparators, any CMPSIDL bit set to `1' disables ALL comparators while in Idle mode. bit 12-9 Reserved: Read as `0' bit 8 DACOE: DAC Output Enable 1 = DAC analog voltage is output to DACOUT pin(1) 0 = DAC analog voltage is not connected to DACOUT pin bit 7-6 INSEL<1:0>: Input Source Select for Comparator bits 00 = Select CMPxA input pin 01 = Select CMPxB input pin 10 = Select CMPxC input pin 11 = Select CMPxD input pin bit 5 EXTREF: Enable External Reference bit 1 = External source provides reference to DAC (maximum DAC voltage determined by external voltage source) 0 = Internal reference sources provide reference to DAC (maximum DAC voltage determined by RANGE bit setting) bit 4 Reserved: Read as `0' bit 3 CMPSTAT: Current State of Comparator Output Including CMPPOL Selection bit bit 2 Reserved: Read as `0' bit 1 CMPPOL: Comparator Output Polarity Control bit 1 = Output is inverted 0 = Output is non-inverted bit 0 RANGE: Selects DAC Output Voltage Range bit 1 = High Range: Max DAC Value = AVDD/2, 1.65V at 3.3V AVDD 0 = Low Range: Max DAC Value = INTREF(2) Note 1: 2: DACOUT can be associated only with a single comparator at any given time.

Description DS70318F-page 267 dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 21.2 On-Chip Voltage Regulator 21.3 BOR: Brown-Out Reset The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 devices power their core digital logic at a nominal 2.5V. This can create a conflict for designs that are required to operate at a higher typical voltage, such as 3.3V. To simplify system design, all devices in the dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 families incorporate an on-chip regulator that allows the device to run its core logic from VDD. The Brown-out Reset (BOR) module is based on an internal voltage reference circuit. The main purpose of the BOR module is to generate a device Reset when a brown-out condition occurs. Brown-out conditions are generally caused by glitches on the AC mains (for example, missing portions of the AC cycle waveform due to bad power transmission lines, or voltage sags due to excessive current draw when a large inductive load is turned on). The regulator provides power to the core from the other VDD pins. When the regulator is enabled, a low-ESR (less than 5 ohms) capacitor (such as tantalum or ceramic) must be connected to the VCAP pin (Figure 21-1). This helps to maintain the stability of the regulator. The recommended value for the filter capacitor is provided in Table 24-13 located in Section 24.1 "DC Characteristics". A BOR generates a Reset pulse, which resets the device. The BOR selects the clock source, based on the device Configuration bit values (FNOSC<2:0> and POSCMD<1:0>). Note: It is important for the low-ESR capacitor to be placed as close as possible to the VCAP pin. On a POR, it takes approximately 20 s for the on-chip voltage regulator to generate an output voltage. During this time, designated as TSTARTUP, code execution is disabled. TSTARTUP is applied every time the device resumes operation after any power-down. FIGURE 21-1: CONNECTIONS FOR THE ON-CHIP VOLTAGE REGULATOR(1,2,3) If an oscillator mode is selected, the BOR activates the Oscillator Start-up Timer (OST). The system clock is held until OST expires. If the PLL is used, the clock is held until the LOCK bit (OSCCON<5>) is `1'. Concurrently, the PWRT time-out (TPWRT) is applied before the internal Reset is released. If TPWRT = 0 and a crystal oscillator is being used, then a nominal delay of TFSCM = 100 is applied. The total delay in this case is TFSCM. The BOR Status bit (RCON<1>) is set to indicate that a BOR has occurred. The BOR circuit continues to operate while in Sleep or Idle modes and resets the device should VDD fall below the BOR threshold voltage. 3.3V dsPIC33F VDD VCAP CEFC 10 F Tantalum Note 1: 2: 3: VSS These are typical operating voltages. Refer to Table 24-13 located in Section 24.1 "DC Characteristics" for the full operating ranges of VDD. It is important for the low-ESR capacitor to be placed as close as possible to the VCAP pin. Typical VCAP pin voltage = 2.5V when VDD VDDMIN.

When the WDT is enabled, the clock source is also enabled. 21.4.1 PRESCALER/POSTSCALER The nominal WDT clock source from LPRC is 32 kHz. This feeds a prescaler than can be configured for either 5-bit (divide-by-32) or 7-bit (divide-by-128) operation. The prescaler is set by the WDTPRE Configuration bit. With a 32 kHz input, the prescaler yields a nominal WDT time-out period (TWDT) of 1 ms in 5-bit mode, or 4 ms in 7-bit mode. A variable postscaler divides down the WDT prescaler output and allows for a wide range of time-out periods. The postscaler is controlled by the WDTPOST<3:0> Configuration bits (FWDT<3:0>) which allow the selection of 16 settings, from 1:1 to 1:32,768. Using the prescaler and postscaler, time-out periods ranging from 1 ms to 131 seconds can be achieved. The WDT, prescaler and postscaler are reset: * On any device Reset * On the completion of a clock switch, whether invoked by software (i.e., setting the OSWEN bit after changing the NOSC<2:0> bits) or by hardware (i.e., Fail-Safe Clock Monitor) * When a PWRSAV instruction is executed (i.e., Sleep or Idle mode is entered) * When the device exits Sleep or Idle mode to resume normal operation * By a CLRWDT instruction during normal execution Note: SLEEP AND IDLE MODES If the WDT is enabled, it will continue to run during Sleep or Idle modes. When the WDT time-out occurs, the device will wake the device and code execution will continue from where the PWRSAV instruction was executed. The corresponding SLEEP bit (RCON<3>) or IDLE bit (RCON<2>) will need to be cleared in software after the device wakes up. 21.4.3 ENABLING WDT The WDT is enabled or disabled by the FWDTEN Configuration bit in the FWDT Configuration register. When the FWDTEN Configuration bit is set, the WDT is always enabled. The WDT can be optionally controlled in software when the FWDTEN Configuration bit has been programmed to `0'. The WDT is enabled in software by setting the SWDTEN control bit (RCON<5>). The SWDTEN control bit is cleared on any device Reset. The software WDT option allows the user application to enable the WDT for critical code segments and disable the WDT during non-critical segments for maximum power savings. Note: If the WINDIS bit (FWDT<6>) is cleared, the CLRWDT instruction should be executed by the application software only during the last 1/4 of the WDT period. This CLRWDT window can be determined by using a timer. If a CLRWDT instruction is executed before this window, a WDT Reset occurs. The WDT flag bit, WDTO (RCON<4>), is not automatically cleared following a WDT time-out. To detect subsequent WDT events, the flag must be cleared in software. The CLRWDT and PWRSAV instructions clear the prescaler and postscaler counts when executed.

Detailed information on this interface will be provided in future revisions of the document. 21.6 In-Circuit Serial Programming The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 family of digital signal controllers can be serially programmed while in the end application circuit. This is done with two lines for clock and data and three other lines for power, ground and the programming sequence. Serial programming allows customers to manufacture boards with unprogrammed devices and then program the digital signal controller just before shipping the product. Serial programming also allows the most recent firmware or a custom firmware to be programmed. Refer to the "dsPIC33F/PIC24H Flash Programming Specification" (DS70152) for details about In-Circuit Serial Programming (ICSP). 21.7 In-Circuit Debugger The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 devices provide simple debugging functionality through the PGECx (Emulation/Debug Clock) and PGEDx (Emulation/Debug Data) pin functions. Any of the three pairs of debugging clock/data pins can be used: * PGEC1 and PGED1 * PGEC2 and PGED2 * PGEC3 and PGED3 To use the in-circuit debugger function of the device, the design must implement ICSP connections to MCLR, VDD, VSS, and the PGECx/PGEDx pin pair. In addition, when the feature is enabled, 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. Any of the three pairs of programming clock/data pins can be used: * PGEC1 and PGED1 * PGEC2 and PGED2 * PGEC3 and PGED3 DS70318F-page 270 (c) 2008-2012 Microchip Technology Inc. dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 21.8 Code Protection and CodeGuardTM Security The code protection features are controlled by the Configuration registers: FBS and FGS. The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 devices offer the intermediate implementation of CodeGuardTM Security. CodeGuard Security enables multiple parties to securely share resources (memory, interrupts and peripherals) on a single chip. This feature helps protect individual Intellectual Property (IP) in collaborative system designs. Secure segment and RAM protection is not implemented in dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 devices. Note: Refer to Section 23. "CodeGuardTM Security" (DS70199) for further information on CodeGuard Security usage, configuration and operation. When coupled with software encryption libraries, CodeGuardTM Security can be used to securely update Flash even when multiple IPs reside on a single chip.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to the latest sections in the "dsPIC33F/PIC24H Family Reference Manual", which are available on the Microchip web site (www.microchip.com). The dsPIC33F instruction set is identical to that of the dsPIC30F. 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 basic categories: * * * * * Word or byte-oriented operations Bit-oriented operations Literal operations DSP operations Control operations Table 22-1 shows the general symbols used in describing the instructions. The dsPIC33F instruction set summary in Table 22-2 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 second source operand, which is typically 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-oriented file register instructions have two operands: * The file register specified by the value, `f' * The destination, which could be either the file register, `f', or the W0 register, which is denoted as `WREG' (c) 2008-2012 Microchip Technology Inc. Most bit-oriented instructions (including rotate/shift instructions) have two operands: simple * 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 literal instructions that involve data movement can use some of the following operands: * A literal value to be loaded into a W register or file register (specified by `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 address modifier * The second source operand, which is a literal value * The destination 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 can use some of the following operands: * The accumulator (A or B) to be used (required operand) * The W registers to be used as the two operands * The X and Y address space prefetch operations * The X and Y address space prefetch destinations * The accumulator write-back destination The other DSP instructions do not involve any multiplication and can include: * The accumulator to be used (required) * The source or destination operand (designated as Wso or Wdo, respectively) with or without an address modifier * The amount of shift specified by a W register, `Wn', or a literal value The control instructions can use some of the following operands: * A program memory address * The mode of the table read and table write instructions DS70318F-page 273 dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 Most instructions are a single word. Certain double-word instructions are designed to provide all the required information in these 48 bits. In the second word, the 8 MSbs are `0's. If this second word is executed as an instruction (by itself), it will execute as a NOP. The double-word instructions execute in two instruction cycles. Most single-word instructions are executed in a single instruction cycle, unless a conditional test is true, or the program counter is changed as a result of the instruction. In these cases, the execution takes two instruction cycles with the additional instruction cycle(s) executed as a NOP. Notable exceptions are the BRA TABLE 22-1: (unconditional/computed branch), indirect CALL/GOTO, all table reads and writes and RETURN/RETFIE instructions, which are single-word instructions but take two or three 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. Note: For more details on the instruction set, refer to the "16-bit MCU and DSC Programmer's Reference Manual" (DS70157).

It features a large LCD display (128 x 64) for menus and error messages and a modular, detachable socket assembly to support various package types. The ICSPTM cable assembly is included as a standard item. In Stand-Alone mode, the MPLAB PM3 Device Programmer can read, verify and program PIC devices without a PC connection. It can also set code protection in this mode. The MPLAB PM3 connects to the host PC via an RS-232 or USB cable. The MPLAB PM3 has high-speed communications and optimized algorithms for quick programming of large memory devices and incorporates an MMC card for file storage and data applications. DS70318F-page 284 The boards support a variety of features, including LEDs, temperature sensors, switches, speakers, RS-232 interfaces, LCD displays, potentiometers and additional EEPROM memory. The demonstration and development boards can be used in teaching environments, for prototyping custom circuits and for learning about various microcontroller applications. In addition to the PICDEMTM and dsPICDEMTM demonstration/development board series of circuits, Microchip has a line of evaluation kits and demonstration software for analog filter design, KEELOQ(R) security ICs, CAN, IrDA(R), PowerSmart battery management, SEEVAL(R) evaluation system, Sigma-Delta ADC, flow rate sensing, plus many more. Also available are starter kits that contain everything needed to experience the specified device. This usually includes a single application and debug capability, all on one board.

Instruction cycle period (TCY) equals two times the input oscillator time-base period. All specified values are based on characterization data for that particular oscillator type under standard operating conditions with the device executing code. Exceeding these specified limits may result in an unstable oscillator operation and/or higher than expected current consumption. All devices are tested to operate at "min." values with an external clock applied to the OSC1/CLKI pin. When an external clock input is used, the "max." cycle time limit is "DC" (no clock) for all devices. Measurements are taken in EC mode. The CLKO signal is measured on the OSC2 pin.

Note: Programming of the Flash memory is not allowed above 125C. The specifications between -40C to +150C are identical to those shown in Section 24.0 "Electrical Characteristics" for operation between -40C to +125C, with the exception of the parameters listed in this section. Parameters in this section begin with an H, which denotes High temperature. For example, parameter DC10 in Section 24.0 "Electrical Characteristics" is the Industrial and Extended temperature equivalent of HDC10. Absolute maximum ratings for the dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04 high temperature devices are listed below. Exposure to these maximum rating conditions for extended periods can affect device reliability.
