Description
IRQn Enable (n = 7 to 0)
The IRQn interrupt request is enabled when this
bit is 1.
Description
[Setting condition]
When the interrupt source selected by the ISCR
registers occurs
[Clearing conditions]
When 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 (n = 7 to 0) *
When IRQn interrupt exception handling is
executed when falling-edge, rising-edge, or
both-edge detection is set *
