Section 5 Interrupt Controller
5.2.5
ISR is an 8-bit readable/writable register that indicates the status of IRQ7 to IRQ0 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.

IRQ Status Register (ISR)
Description
[Clearing conditions]

:

:
Cleared by reading IRQnF flag when IRQnF = 1, then writing 0 to IRQnF flag
When interrupt exception handling is executed when low-level detection is set
(IRQnSCB = IRQnSCA = 0) and IRQn input is high
When IRQn interrupt exception handling is executed when falling, rising, or both-
edge detection is set (IRQnSCB = 1 or IRQnSCA = 1)
When the DTC is activated by an IRQn interrupt, and the DISEL bit in MRB of the
DTC is cleared to 0
When IRQn input goes low when low-level detection is set (IRQnSCB = IRQnSCA =
0)
When a falling edge occurs in IRQn input when falling edge detection is set
(IRQnSCB = 0, IRQnSCA = 1)
When a rising edge occurs in IRQn input when rising edge detection is set
(IRQnSCB = 1, IRQnSCA = 0)
When a falling or rising edge occurs in IRQn input when both-edge detection is set
(IRQnSCB = IRQnSCA = 1)
