Table of Contents

When an EPA x interrupt occurs, the EPA interrupt priority vector register (EPAIPV) contains a number

that identifies the highest priority, active, multiplexed interrupt source (see Table C-14).

EPAIPV allows software to branch via the TIJMP instruction to the correct interrupt service routine

when EPA x is activated. Reading EPAIPV clears the EPA pending bit for the interrupt associated with

the value in EPAIPV. When all the EPA pending bits are cleared, the EPA x pending bit is also cleared.

These interrupts apply to the 8XC196K x devices only.

Reserved; always write as zeros.

Priority Vector

These bits contain a number from 01H to 14H corresponding to the

highest-priority active interrupt source. This value, when used with the

TIJMP instruction, allows software to branch to the correct interrupt

service routine.
