When hardware detects a pending EPA x interrupt, it sets the corresponding bit in the EPA interrupt
pending (EPA_PEND or EPA_PEND1) registers. 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.
