[Clearing conditions]
• Cleared by reading IRQnF when set to 1, then writing 0 in IRQnF
• When interrupt exception handling is executed while low-level detection
• When IRQn interrupt exception handling is executed while falling, rising,
• When the DTC is activated by an IRQn interrupt, and the DISEL bit in
[Setting conditions]
• When IRQn input goes low when low-level detection is set
• When a falling edge occurs in IRQn input while falling edge detection is
• When a rising edge occurs in IRQn input while rising edge detection is
• When a falling or rising edge occurs in IRQn input while both-edge
is set (IRQnSCB = IRQnSCA = 0) and IRQn input is high
or both-edge detection is set (IRQnSCB = 1 or IRQnSCA = 1)
MRB of the DTC is cleared to 0
(IRQnSCB = IRQnSCA = 0)
set (IRQnSCB = 0, IRQnSCA = 1)
set (IRQnSCB = 1, IRQnSCA = 0)
detection is set (IRQnSCB = IRQnSCA = 1)
