Detection Setting

Description

Level detection

No IRQn interrupt request exists.

Clear conditions: When

IRQn input is high level

Edge detection

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

executed

Level detection

An IRQn interrupt request exists.

Set conditions: When

IRQn input is low level
