After chip enters power down, the following wake-up sources can wake chip up to normal mode.
Wake-Up
Source
Wake-Up Condition
System Can Enter Power-Down Mode Again Condition*
BOD
Brown-Out Detector Interrupt After software writes 1 to clear BOD_INTF (BODCR[4]).
GPIO
GPIO Interrupt
After software write 1 to clear the ISRC[n] bit.
TIMER
Timer Interrupt
After software writes 1 to clear TWF (TISRx[1]) and TIF (TISRx[0]).
WDT
WDT Interrupt
After software writes 1 to clear WTWKF (WTCR[5]) (Write Protect).
RTC
Alarm Interrupt
After software writes 1 to clear AIF (RIIR[0]).
Time Tick Interrupt
After software writes 1 to clear TIF (RIIR[1]).
UART
nCTS wake-up
After software writes 1 to clear DCTSF (UA_MSR[0]).
I
2C
Addressing I
2C device
After software writes 1 to clear WKUPIF (I2CWKUPSTS[0]).
USB
Remote Wake-up
After software writes 1 to clear BUS_STS (USBD_INTSTS[0]).
*User needs to wait this condition before setting PWR_DOWN_EN (PWRCON[7]) and execute WFI to enter Power-down mode.
Table 6-4*User needs to wait this condition before setting PWR_DOWN_EN (PWRCON[7]) and execute WFI to enter Power-
down mode.
Table 6-4 lists the condition about how to enter Power-down mode again for each peripheral.

System Power Distribution
In this chip, the power distribution is divided into three segments.
Analog power from AVDD and AVSS provides the power for analog components
operation.
Digital power from VDD and VSS supplies the power to the internal regulator which
provides a fixed 1.8 V power for digital operation and I/O pins.
