Description
IRQ4 and IRQ3 Flags
Indicate the status of IRQ4 and IRQ3 interrupt
requests.
[Setting condition]
When the interrupt source selected by the ISCR
registers occurs
[Clearing conditions]

Reserved
The write value should always be 0.
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 and IRQn input is
high
When IRQn interrupt exception handling is
executed when falling, rising, or both-edge
detection is set
When the DTC is activated by an IRQn interrupt,
and the DISEL bit in MRB of the DTC is cleared to
0 (H8S/2268 Group only)
