- I have a custom trap handler that I would like to test in Supervisor Mode
- on my A3000. I am using Powervisor to step through the code but as soon as
- I move the address of the handler to tc_TrapData, the computer executes
- the code and stops at the RTE. In order to step through the trap handler
- I would like to put my User program in Supervisor mode so I have access to
- the usp and other privileged instructions. I'm also hoping this will allow
- me to step through the code.
-
- Basically, I would like to set bit 13 of the SR from a user program so
- it will have Supervisor access to the instructions.
-
- Also, are there any other debugging tools that I can use on 680x0 code?
- I use Powervisor and Monitor 1.54.

- Ray.
