5.3.9 Wake-Up Sense Control Register (WUESCR)
Wake-Up Input Interrupt Status Register (WUESR)
Wake-Up Enable Register (WER)
WUESCR selects the interrupt source of the wake-up event interrupt inputs (WUE15 to WUE8).
WUESR is an interrupt request flag register. WER enables/disables interrupts.

Wake-Up Event Interrupt Source Select
These bits select the source that generates an
interrupt request at wake-up event interrupt inputs
(WUE15 to WUE8).
0: Interrupt request generated at falling edge of
WUEn input
1: Interrupt request generated at rising edge of
WUEn input
(n = 15 to 8)

Wake-Up Input Interrupt (WUE15 to WUE8)
Request Flag Register
These bits are status flags that indicate that wake-
up input interrupts (WUE15 to WUE8) are
requested.
[Setting condition]
• When a wake-up input interrupt is generated
[Clearing condition]
• When 0 is written after reading 1
Note: * Only 0 can be written to clear the flag.
