NOTE: 1. This register is maintained on the battery well and will be maintained with both core and standby power loss.
Reset only with RTC_RST#.
2. Field is standby powered and unaffected by SB_POWEROK or P_RST#. Reset only with RSMRST#.

SB_POWEROK not lost in S0/S1 flag. Set by any programming
of SLP_TYP. Cleared by SB_POWEROK deasserted while the
system is programmed for S0 or S1 state. Bits are to be used
to track power transitions and whether power failed before
or during a resume.
