To Step The Processor - HP MC68040 User Manual

To step the processor

• Choose Execution→Step Source or Execution→Step Instruction. Select the
starting point for processor stepping from the associated submenu. If you will enter
a command that requires a starting address, enter that address in the entry buffer
before entering the command.
• Using the command line, enter commands as follows:
•
To step the processor one instruction from the current program counter value,
enter:
step
•
To step one line of high level source, enter:
step source
•
To step the processor <count> number of times from the current program
counter value, enter:
step <count>
•
To step the processor one instruction from an address given by <address>, type:
step from <address>
•
To step the processor <count> number of times from an address given by
<address>, type:
step <count> from <address>
•
To suppress display of registers for intermediate steps of a multi-step
execution, add the silently parameter after the step <count> command.
(<count> must be greater than one.) This is only effective when stepping is
done in the same interface displaying registers.
The step command lets you single-step the processor through program code. Step
Source executes one line in your high-level source program; Step Instruction
executes one line of your assembly language program.
