Your Target Design
Typically, this is a wire-wrapped or printed-circuit
prototype that includes a 68PLCC socket that you can
connect the emulator’s pod.

LIMITATIONS
1. Switching emulators without quitting the GUI is not
supported and may cause unexpected results.
2. The emulator breakpoint hardware does not
distinguish between instruction and data fetches.
Consequently, 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 the breakpoint at %0008 and click GO causes
the code to break at %0004 due to the data fetch
address match during the prior instruction. This does
not occur when Animate Mode is on because the GUI
is not using the hardware breakpoints when in
Animate Mode.
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
instructions when entered in the In-Line Assembler
(Debug window). As a workaround, use “LD
STACK,xxx” for PUSH and “LD xxx,STACK” for POP.
7. Please consult the “P_AND_L.TXT” and
“OTPPROG.TXT files for latest updates.
