5.2.3 IRQ Status Register (ISR)
ISR is an 8-bit readable/writable register that indicates the status of IRQ0 to IRQ7 interrupt
requests.
ISR is initialized to H'00 by a reset and in hardware standby mode.
Bits 7 to 0—IRQ7 to IRQ0 Flags (IRQ7F to IRQ0F): These bits indicate the status of IRQ7 to
IRQ0 interrupt requests.
Bits 7 to 0
IRQ7F to IRQ0F
Description
0
[Clearing conditions]
(Initial value)
0 is written in IRQnF after reading the IRQnF flag when IRQnF = 1.
IRQnSC = 0, IRQn input is high, and interrupt exception handling is carried out.
IRQnSC = 1 and IRQn interrupt exception handling is carried out.
1
[Setting conditions]
IRQnSC = 0 and IRQn input is low.
IRQnSC = 1 and IRQn input changes from high to low.
Note: n = 7 to 0
