Description
[Setting condition]
When the interrupt source selected by ISCR 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
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 = 15 to 0)
