[Setting 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
(IRQnSCB = IRQnSCA = 0) and
When IRQn interrupt exception handling is executed when falling, rising, or both-
edge detection is set (IRQnSCB = 1 or IRQnSCA = 1)
When the DTC is activated by an IRQn interrupt, and the DISEL bit in MRB of the
DTC is cleared to 0
