I am using a 68000 based SBC for the VMEbus to debug prototype hardware for
this bus. To debug the interrupting capablilities of my hardware, I need
to stop the 68000 and wait for an interrupt (level=4).
This works:
0010AC MOVE #2300,SR
0010B0 JMP $10B0
This doesn't:
0010AC STOP #2300
Now according to my book, STOP stops the 68k from fetching and executing
instructions, until an exception comes along. If an interrupt request occurs,
with a high enough level, an interrupt exception occurs.
So, as far I can tell, both examples of code should have the same result.
What am I doing wrong??
