KWUPST
(0xFFFF_F910)
19.5 Detection of Key Input Interrupts and Clearance of Requests
When KEYnEN is set to 1 and an active signal is input to KEYn, the KEYINTn channel that
corresponds to KWUPST is set to "1," indicating that an interrupt is generated. The KWUPST is the
read-only register. Reading this register clears the corresponding bit that has been set to "1".
If the active state is set to the high or low level, the corresponding bit of the KWUPINTn register
remains "1" after it is read, unless the external input is withdrawn.
