Description
IRQ7 to IRQ0 Flags
Indicates the status of IRQ7 to IRQ0 interrupt requests.
[Setting condition]
When the interrupt source selected by the ISCRH, or
ISCRL occurs
[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 and IRQn input is high level
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
