Section 5 Interrupt Controller
5.2.5
ISR is an 8-bit readable/writable register that indicates the status of IRQ5 to IRQ0 interrupt
requests.
ISR is initialized to H'00 by a reset and in hardware standby mode.
They are not initialized in software standby mode.
Bits 7 and 6—Reserved: These bits are always read as 0.
Bits 5 to 0—IRQ5 to IRQ0 Flags (IRQ5F to IRQ0F): These bits indicate the status of IRQ5 to
IRQ0 interrupt requests.
