Personality File Usage
Your development system uses a specific personality file for the MCU
type being emulated. For example, to emulate an MC68HC(8)05P18
MCU, the system uses the personality file 00022Vxx.MEM. Debugger
software loads this personality file upon power up.
NOTE:
Note that personality file names follow the pattern
00ZZZVxx.MEM, where ZZZ is the EM identifier or MCU name
and xx is the version of the file.
MC68HC(8)05P18 Emulation
NOTE:
Be aware that if the computer operating properly (COP) mask
option has been selected as enabled, your code must clear
the COP watchdog timer counter to avoid a COP reset. The
counter is cleared by writing a logical 0 to bit 0 at location
$3FF0. This should be the first check when code is not
operating as expected.
The MC68HC(8)05P18 MCU is emulated on the M68EM05P18
emulation module. The resident MCU (socket XU5) should be an
EEPROM device (an MC68HC805P18).
The following paragraphs detail known differences between the
performance of an MC68HC805P18 MCU run in single-chip operation
versus the way certain features will perform during emulation.
