Wake-up Selector For MCU
This register contains pointers to 4 events which are routed to AON_WUC as wakeup sources for MCU. AON_WUC will start a wakeup sequence for the MCU domain when either of the 4 selected events are asserted. A wakeup sequence will guarantee that the MCU power switches are turned on, LDO resources are available and SCLK_HF is available and selected as clock source for MCU.
Note: It is recommended ( or required when AON_WUC:MCUCLK.PWR_DWN_SRC=NONE) to also setup a wakeup event here before MCU is requesting powerdown. ( PRCM requests uLDO, see conditions in PRCM:VDCTL.ULDO ) as it will speed up the wakeup procedure.
