7: ISR address is read by CPU for branching
8, 9: PEND and POST bits are cleared respectively after receiving the IRA from core
10: IRA bit is cleared after completing the current instruction and starting the instruction execution from ISR location (Takes 7 cycles)
11: IRC is set to indicate the completion of ISR, Active int. status is restored with previous status
The total interrupt latency (ISR execution)
