On exit from a power-on reset, the PORSF flag (RSTSRC.1) is set by hardware to logic 1. When PORSF is
set, all of the other reset flags in the RSTSRC Register are indeterminate (PORSF is cleared by all other
resets). Since all resets cause program execution to begin at the same location (0x0000), software can
read the PORSF flag to determine if a power-up was the cause of reset. The contents of internal data
memory should be assumed to be undefined after a power-on reset.
The VBAT supply monitor can be disabled to save power by writing ‘1’ to the MONDIS (PMU0MD.5) bit.
When the VBAT supply monitor is disabled, all reset sources will trigger a full POR and will re-enable the
VBAT supply monitor.
Note: Si1010/1/2/3 have the VBAT signal internally connected to VDD_MCU.
