EPA Pending Registers
Figures 7-5 and 7-6 illustrate the EPA pending registers, EPA_PEND and EPA_PEND1, for the
8XC196L
x
microcontroller family.
EPA_PEND
Address:
Reset State:
1FA2H
0000H
When hardware detects a pending EPA
6–9 or OVR0–3, 8–9 interrupt request, it sets the
corresponding bit in the EPA interrupt pending register (EPA_PEND or EPA_PEND1). The EPAIPV
register contains a number that identifies the highest priority, active, shared interrupt source. When
EPAIPV is read, the EPA interrupt pending bit associated with the EPAIPV priority value is cleared.

Any set bit indicates that the corresponding EPAx interrupt source is pending. The bit is
cleared when software reads the EPA interrupt priority vector register (EPAIPV).
Bits 2–5 and 14–15 are reserved on the 8XC196L
x
device family. For compatibility with future
devices, write zeros to these bits.

EPA_PEND1
Address:
Reset State:
1FA6H
00H
When hardware detects a pending EPA
x
interrupt, it sets the corresponding bit in the EPA interrupt
pending register (EPA_PEND or EPA_PEND1). The EPAIPV register contains a number that
identifies the highest priority, active, multiplexed interrupt source. When EPAIPV is read, the EPA
interrupt pending bit associated with the EPAIPV priority value is cleared.

Any set bit indicates that the corresponding EPAxinterrupt source is pending. The bit is
