Commands
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 software breakpoint one
instruction beyond the current program counter and then executes the target code. This command
only works when executing code in SRAM.
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:
