Interrupts and Events Registers
4.7.1.1 MCUWUSEL Register (Offset = 0h) [reset = 3F3F3F3Fh]
MCUWUSEL is shown in
Wake-up Selector For MCU.
This register contains pointers to 4 events that are routed to AON_WUC as wake-up sources for MCU.
AON_WUC starts a wake-up sequence for the MCU domain when either of the 4 selected events are
asserted. A wake-up sequence ensures that the MCU power switches are turned on, LDO resources are
available, and that 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 set up
a wake-up event here before MCU is requesting power down. (PRCM requests uLDO, see conditions in
PRCM:VDCTL.ULDO) as it speeds up the wake-up procedure.
