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