The NMI pin is not bonded out on the 8XC196L
x
. 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.
