Hi, My application is using two interrupts, the SWI and the OC7. My code executes for just a fraction of a second before it aborts. In the D-Bug12 window it gives me the message: BGND Instruction Executed It also gives me the contents of the registers. My interrupts don't seem to be working at all. My question for all of you is, is there anything in the D-bug12 that uses interrupts? Could I be fighting D-bug12 with my interrupts? Thanks, Shayne C. Rich Autonomous Solutions, Inc.

Shayne, When D-Bug12 is in POD mode, it does not use any target resources (except the breakpoint module for breakpoints). Have you initialized the interrupt vectors ($FFF6-$FFF7 for SWI & $FFE0-$FFE1 for OC7)? Regards, Gordon "Shayne C. Rich" wrote: > Hi, > > My application is using two interrupts, the SWI and the OC7.
