Section 5 Interrupt Controller
5.2.3
ISR is an 8-bit readable/writable register that indicates the status of IRQ
requests.
ISR is initialized to H'00 by a reset and in hardware standby mode.
Bits 7 and 6—Reserved: These bits can not be modified and are always read as 0.
Bits 5 to 0—IRQ

[Clearing conditions]
0 is written in IRQnF after reading the IRQnF flag when IRQnF = 1.
IRQnSC = 0,
IRQnSC = 1 and IRQn interrupt exception handling is carried out.
