6.3.33 Bank0 R2F: WUCR1 (Wake Up Control Register 1)
Bits 7:
Bit 6 (SPIWE): SPI Wake-up enable bit. Applicable only when SPI works in Slave
Bit 5 (LVDWE): Low Voltage Detect Wake-up Enable bit
Bit 4 (ICWE):
Bit 3:
Bits 2~1 (CMP2WE~CMP1WE): Comparator 2~1 Wake-up enable bits
Bit 0 (EXWE): External Interrupts Wake-up Function Enable bit
6.3.34 Bank0 R30~R31 (Not Used)

Not used, fixed to “0” all the time.
mode.
0: Disable SPI Wake up
1: Enable SPI Wake up.
Port 6 Input Status Change Wake-up enable bit
0: Disable Port 6 input status change Wake-up
1: Enable Port 6 input status change Wake-up
When the Port 6 input status change is used to enter interrupt vector
or to wake-up IC from Sleep/Idle mode, the ICWE bit must be set to
“Enable“.
Not used, fixed to “0” all the time.
0: Disable Comparator Wake-up
1: Enable Comparator Wake-up
When the Comparators 2~1 output status change is used to enter an
interrupt vector or to Wake-up the IC from Sleep, the CMPWE bit
must be set to “Enable“.
0: Disable external interrupt Wake-up
1: Enable external interrupt Wake-up
When the External Interrupt status changed is used to enter an
interrupt vector or to Wake-up the IC from Sleep, the EXWE bits
must be set to “Enable“.
