6. Wakeup Interrupt Request Register (IWPR)
IWPR is an 8-bit read/write register containing wakeup interrupt request flags. When one of pins
WKP
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.
