LIMITATIONS
1. Switching emulators without quitting the GUI is not
supported and causes unexpected results.
2. The maximum loadable symbols is 32,768 (provided
there is enough system memory).
3. Although version 3.00 or higher of the GUI may sup-
port 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 maxi-
mum usable rate is determined by the users tolerance
of the frequency of communication errors.
4. 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.
5. The ICEBOX breakpoint hardware cannot distinguish
between instruction and data fetches. Consequently,
the breakpoint hardware triggers when the address
specified matches either an instruction or data fetch.
Example:
0000
0002
0003
0004
0005
0006
0008
LD A, #%0006
ADD A,#%0002
LD Y,@A
NOP
NOP
JP %0000
NOP
Setting a breakpoint at %0008 and clicking GO
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.
6. The STEP OVER button sets a temporary breakpoint
on the next instruction and starts execution of the cur-
rent instruction. If control does not return to the tem-
porary breakpoint in a fixed amount of time, a ZiLOG
ICEBOX TARGET PROGRAM EXECUTION ERROR
message occurs. As a workaround, the user should
simply set a regular breakpoint on the next instruction
and click on the GO button (perform this action in
place of using the STEP OVER function).
