Setting and Clearing Conditions
[Clearing conditions]
Read IRQnF when IRQnF = 1, then write 0 in IRQnF.
IRQnSC = 0, IRQn input is high, and interrupt exception
handling is carried out.
IRQnSC = 1 and IRQn interrupt exception handling is
carried out.
1
[Setting conditions]
IRQnSC = 0 and IRQn input is low.
IRQnSC = 1 and IRQn input changes from high to low.
(n = 7 to 0)
