[Setting condition]

• When the interrupt selected by ISCR occurs

[Clearing conditions]

• Writing 0 after reading IRQnF = 1 (n = 11 to 0)

• When interrupt exception handling is executed while

low-level sensing is selected and

IRQn input is high

• When IRQn interrupt exception handling is executed

while falling-, rising-, or both-edge sensing is

selected

• When the DTC is activated by an IRQn interrupt,

and the DISEL bit in MRB of the DTC is cleared to 0

Note:

Only 0 can be written, to clear the flag.
