IRQ Interrupt Request

These bits indicate the status of the IRQ7 to IRQ0

interrupt requests.

Level detection:

0: IRQn interrupt request has not occurred

[Clearing condition]

• IRQn input is high

1: IRQn interrupt has occurred

[Setting condition]

• IRQn input is low

Edge detection:

0: IRQn interrupt request is not detected

[Clearing conditions]

• Cleared by reading IRQnF while IRQnF = 1, then

writing 0 to IRQnF

• Cleared by executing IRQn interrupt exception

handling

1: IRQn interrupt request is detected

[Setting condition]

• Edge corresponding to IRQn1S or IRQn0S of

ICR1 has occurred at IRQn pin

[Legend]

n = 7 to 0
