Using the Monitor/Debug Firmware
STEP
Step Over
Usage:
STEP
The STEP command can be used to “step over” a subroutine call, rather than tracing every instruction in
the subroutine. The ST command sets a temporary breakpoint one instruction beyond the current program
counter and then executes the target code.
The STEP command can be used to “step over” BSR and JSR instructions.
The STEP command will work for other instructions as well, but note that if the STEP command is used
with an instruction that will not return, i.e. BRA, then the temporary breakpoint may never be encountered
and dBUG may never regain control.
Examples:
To pass over a subroutine call, the command is:
