Wake-up sources in Power-down mode:
RTC, WDT, I²C, Timer, UART, USCI, BOD, VDET, GPIO, and ACMP.
After chip enters power down, the following wake-up sources can wake chip up to normal mode.
Table 6.2-4 lists the condition about how to enter Power-down mode again for each peripheral.
*User needs to wait this condition before setting PDEN(CLK_PWRCTL[7]) and execute WFI to
enter Power-down mode.
