IWPR is an 8-bit read/write register containing wakeup interrupt request flags. When one of pins

WKP

7 to

WKP

0 is designated for wakeup input and a rising or falling edge is input at that pin, the

corresponding flag in IWPR is set to 1. A flag is not cleared automatically when the

corresponding interrupt is accepted. Flags must be cleared by writing 0.

Description

Clearing conditions:

(initial value)

When IWPFn= 1, it is cleared by writing 0

Setting conditions:

When pin

WKPn is designated for wakeup input and a rising or falling edge is input at

that pin

(n = 7 to 0)
