GENERAL DESCRIPTION

ZiLOG’s in-circuit emulators are interactive Windows-ori-

ented development tools that provide a real-time environ-

ment for developing and debugging software. Included with

each of ZiLOG’s emulators is a powerful, full-featured mac-

ro cross assembler. When used in conjunction with the

Z89323 Emulator, this tool is designed to enhance program-

mer productivity.

The Emulator provides a hardware platform that is a signif-

icant improvement compared to software simulators. The

Emulator is faster in operation than simulators, making it

more practical for code development.

The Z89323 Emulator, which supports the Z89323 family

of DSP processors listed above, provides essential timing

and I/O circuitry to simplify user emulation of the prototype

hardware and software product.

The Z89323 Emulator can be connected to the serial port

(COM1, COM2, COM3, or COM4) of the host computer,

and uses Graphical User Interface (GUI) software.

PRECAUTIONS

1. GUI software versions prior to 3.00 are incompatible

with hardware containing BOOTROM 3.00. The GUI

software may still boot; however, the software could

fail at some later point.

2. When simultaneously running two different GUI ver-

sions on two different Communication Ports, the

former executed version is used for both emulators.

These are typical Windows O/S bugs.

3. The emulator cannot be operated while performing

ESD/EMI testing on the target board.

4. The GUI occasionally indicates

Executing

after a

HALT instruction. Pushing the GO button also indi-

cates

Executing

. (

Executing

displays at the caption

bar of the Debug window.)

5. Ensure that the target cable is correctly aligned (pin-1

to pin-1) before inserting into the target system. Incor-

rect alignment may damage the emulator and/or the

target system.

6. Do not start the emulator with an OTP device in the

programming socket. This action may cause the emu-

lator to not start up correctly.

7. A shorted PLCC or DIP OTP can crash the emulator

when inserted into the OTP programming socket. If a

PLCC part is inserted in such a way as to cause a tem-

porary short, then functionality is lost. An attempt to

perform BLANK CHECK on such a part causes the

“hourglass” to run incessantly. The Windows applica-

tion must be reset and restarted.

8. The status color bar in the OTP dialog box clears when

a new window opens on top of it.

9. Do not press the emulator MASTER RESET when the

emulator is in the OTP dialog for programming. If

MASTER RESET is pressed while the GUI is doing

OTP programming, close the OTP dialog box and re-

open it to reload the information back to the hardware.

Note:

The emulator is really sitting idle, although the Com-

mand Status shows “Processing” after the GUI reestab-

lishes the communication link when “Retry” was

selected in the “Out of Synchronization with the Emula-

tor” dialog box.

10. When device serialization is enabled in the OTP dia-

log, the GUI copies the current serial number to code

memory immediately before performing a VERIFY

operation. If this behavior is undesirable, then device

serialization should be disabled prior to invoking the

VERIFY operation.

11. Do not use the OTP operation while in the Debug’s

trace and/or animation mode.

12. Option selections for the OTP are not cleared after

changing a Device selection (applies to DSPICE

GUI).

13. The

Edit|Fill|Memory

Decimal radix option will not

accept entry of more than 9,999 for the Fill Value.

Please use the Hexadecimal radix option when using a

fill value of more than 9,999 decimal.

LIMITATIONS

1. Switching Emulators without quitting the GUI is not

supported and may cause unexpected results.

2. The Emulator breakpoint hardware does not distin-

guish between instruction and data fetches. Conse-

quently, the breakpoint hardware triggers when the

address specified matches either an instruction or data

fetch.

Example:

0000 LD A, #%0006

0002 ADD A,#%0002

0003 LD Y,@A

0004 NOP

0005 NOP

0006 JP %0000

0008 NOP

Setting a breakpoint at %0008 and clicking

causes the code to break at %0004 due to the data

fetch address match during the prior instruction.

This anomaly does not occur during Animate mode

because Animate mode does not use hardware

breakpoints.

ROM PROTECT

option programming is temporarily

disabled.

4. The maximum loadable symbols is 32,768, provided

there is enough system resource (memory).

5. Although GUI 3.00 and later support baud rates up to

57.6K baud, the actual maximum usable rate may be

less due to limitations of the users hardware and/or

system software setup. The maximum usable rate is

determined by the users tolerance of the frequency of

communication errors.

6. The GUI does not recognize the PUSH and POP in-

structions when entered in the In-Line Assembler (De-

bug window). As a workaround, use

LD STACK,xxx

for PUSH and

LD xxx,STACK

for POP.
