IWPR is an 8-bit read/write register containing wakeup interrupt request flags. When one of pins
WKP₇ to WKP₀ 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 condition:
When IWPFn= 1, it is cleared by writing 0
