MMDS05 CONFIGURATION AND OPERATION
2.2 THE EMULATED MCU
Your MMDS05 system uses a specific personality file for the MCU type being emulated.
For example, to emulate an MC68HC05F4 or MC68HC705F4 MCU, the system uses
personality file 00220Vxx.MEM this file contains device specific information such as
memory map, required by the MMDS05 for correct operation.
Table 2-1 lists all the personality files that pertain to the F4EM. 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.

MMDS05 software loads the default personality file for the EM board installed on power-
up. To manually load a different personality file, use the LOADMEM command. (For more
information about the LOADMEM command, see the explanation in the MMDS05
operations manual.)
Alternatively, you can insert the line LOADMEM 00ZZZVxx.MEM in the STARTUP.05
script file. This way, the system automatically loads the specified personality file as part of
system start-up. (For more information about the STARTUP.05 script file, see the SCRIPT
command explanation in the MMDS05 operations manual.)
Note:- For correct operation you must install the personality file in the same directory as the
MMDS05 software, place only the latest versions of these files in this directory. If the
personality file required for the EM board is not in the same directory, the MMDS05 will
prompt you for one. You may select one anywhere on the drive on which the MMDS05
software resides.
2.2.1 MC68HC705F4 Emulation Limitations
The open-drain outputs on the port pins PB0 and PB1 will not match the silicon precisely.
The COP reset circuitry will function correctly but only if bit X of location $1F equals 1.
For more information about the MC68HC705F4, see the corresponding technical data books.
2.2.2 MC68HC05F4 Emulation Limitations
Limitations are as per 2.2.1.
