4.7.1.2 AUXWUSEL Register (Offset = 4h) [reset = 3F3F3Fh]
AUXWUSEL is shown in
Wake-up Selector For AUX.
This register contains pointers to 3 events that are routed to AON_WUC as wake-up sources for AUX.
AON_WUC starts a wake-up sequence for the AUX domain when either of the 3 selected events are
asserted. A wake-up sequence ensures that the AUX power switches are turned on, LDO resources are
available, and SCLK_HF is available and selected as clock source for AUX.
Note: It is recommended (or required when AON_WUC:AUXCLK.PWR_DWN_SRC=NONE) to also set up
a wake-up event here before AUX is requesting power down. (AUX_WUC:PWRDWNREQ.REQ is
asserted) as it speeds up the wake-up procedure.
