HP 64751 User Manual page 157

The default programming of the DE-SIM matches the reset values of the 68340
SIM (refer to the Motorola MC68340 Integrated Processor User's Manual for
specific values).
If desired, the programming of the DE-SIM can be transferred into the 68340 SIM
with the sync_sim_registers to_68340_from_config command. This happens
automatically each time a break to the monitor from emulation reset occurs. This
ensures that the 68340 is prepared to properly access memory when a program is
downloaded to the emulator.
Alternatively, the emulator's DE-SIM can be programmed from the 68340 SIM
with the sync_sim_registers from_68340_to_config command. This is useful if
initialization code that configures the 68340 SIM exists, but you don't what its
values are. In this case, you can use the default configuration, run from reset to
execute the initialization code, and use the sync_sim_registers
from_68340_to_config command to configure the emulator to match the 68340
SIM.
At any time, you can verify if the SIM and DE-SIM are programmed the same with
the sync_sim_registers difference command. Any differences between the two
register sets will be listed.
It should be noted that the DE-SIM module is programmed solely from the
CF_SIM register set and is therefore static with respect to the application program.
No attempt is made to update the programming of the DE-SIM by tracking
instructions that will program the 68340 SIM.
