RESET
Use the RESET command to specify the reset operation level when a RESET exception is
detected by the processor. Press the RESET switch on the M68300PFB platform board to
generate a reset exception.
Two RESET levels are available:
COLD This is the standard mode of operation, and is the default at power-up. In
this mode all the static variables are initialized every time a reset is
executed.
WARM In this mode all the static variables are preserved when a reset exception
occurs. This is convenient for keeping breakpoints, offset register values,
the target register state, and any other static variables in the system.
EXAMPLE
CPU32Bug>RESET<CR>
Cold/Warm Start = C (C/W)? W<CR>
Set to warm start.

Press the RESET pushbutton.

RM Register Modify RM
3.27 REGISTER MODIFY
RM <reg>
Use the RM command to display and change the target registers. The RM command functions in
essentially the same way as the MM command, and the same step control characters are used to
control the display/change session. Refer to the MM command.
EXAMPLES
CPU32Bug>RM D4<CR>
D5 =12345678? ABCDEF^<CR>
Modify register and backup.
D4 =00000000? 3000.<CR> Modify register and exit.

CPU32Bug>rm sfc<CR>
SFC =7=CS ? 1=<CR>
Modify register and re-open.
