Chapter 4: Configuring the Emulator
Setting the Debug/Trace Options
To specify which TRAP instruction is used for
software breakpoints
• Enter a value in response to the "Trap number for software breakpoint (0..0FH)?"
question.
You can answer with values from 0 through 0FH to specify the particular TRAP
instruction used for software breakpoints. The value indicates the exception vector
to use in processing the trap.
Use this configuration option if you have inserted other TRAP instructions in your
code with varying exception vector values. The configuration option allows you to
specify a different exception vector than the ones previously inserted. The
emulation monitor then responds normally to execution of a breakpoint.
When you change the answer to this configuration question, any software
breakpoints currently defined are disabled. (The software breakpoint trap
instructions currently in memory would be different than the new value you have
specified.)
Note that any breakpoints defined in target memory must be cleared (by the
software breakpoints command) before the TRAP instruction is changed.
