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

(n = 7 to 0)
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
When IRQn interrupt exception handling is executed
when falling-edge, rising-edge, or both-edge
detection is set
