Description
No IRQn interrupt request exists.
Clear conditions: When IRQn input is high level
No IRQn interrupt request was detected. (initial value)
Clear conditions:
1. When a 0 is written after reading IRQnF = 1 status
2. When IRQn interrupt exception processing has been
An IRQn interrupt request exists.
Set conditions: When IRQn input is low level
An IRQn interrupt request was detected.
