•
When the interrupt source selected by the ISCR
registers occurs
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
(n = 5 to 0)
