Bits 7 to 0—IRQ7 to IRQ0 Flags (IRQ7F to IRQ0F): These bits indicate the status of IRQ7 to
IRQ0 interrupt requests.

corresponding flag bit is not automatically cleared even when exception handling, which
is a clear condition, is executed and the bit is held at 1.
(1) When DTCEA3 is set to 1 (ADI is set to an interrupt source), IRQ4F flag is not
(2) When DTCEA2 is set to 1 (ICIA is set to an interrupt source), IRQ5F flag is not
(3) When DTCEA1 is set to 1 (ICIB is set to an interrupt source), IRQ6F flag is not
(4) When DTCEA0 is set to 1 (OCIA is set to an interrupt source), IRQ7F flag is not
When activation interrupt sources of DTC and IRQ interrupts are used with the above
combinations, clear the interrupt flag by software in the interrupt handling routine of the
corresponding IRQ.
Cleared by reading IRQnF when set to 1, then writing 0 in IRQnF
When interrupt exception handling is executed while low-level detection is set
(IRQnSCB = IRQnSCA = 0) and IRQn input is high *
When IRQn interrupt exception handling is executed while falling, rising, or both-edge
detection is set (IRQnSCB = 1 or IRQnSCA = 1) *
When IRQn input goes low when low-level detection is set (IRQnSCB = IRQnSCA = 0)
When a falling edge occurs in IRQn input while falling edge detection is set
(IRQnSCB = 0, IRQnSCA = 1)
When a rising edge occurs in IRQn input while rising edge detection is set
