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
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.
3. 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.
7. Please consult the P_ANDL.TXT and OTPPROG.TXT
files for the latest updates.
