Key-on Wakeup Circuit
KWUPINT
(0xFF00_1A8C)
20.5 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
KWUPINTn is set to “1,” indicating that an interrupt is generated. The KWUPINTn is the read-only register.
Reading this register clears the corresponding bit that has been set to “1” and the interrupt request.
(A clear by KWUPCLR is also possible.）
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after it is read, unless the external input is withdrawn.
