The NMI pin is not bonded out on the 8XC196Lx. To protect against glitches, create a dummy interrupt
service routine that contains a RET instruction.
These interrupts are individually prioritized in the EPAIPV register. Read the EPA pending registers
(EPA_PEND and EPA_PEND1) to determine which source caused the interrupt.
87C196LA, LB only. The 83C196LD has no EPA compare-only channels.
