Description
If set, indicates that an Rx edge event triggered wake-up from PSM2.
Indicates the power supply that is internally connected to V SWOUT (0: V SWOUT = V BAT ; 1: V SWOUT = V DD ).
If set, indicates that V DD power supply is ready for operation.
If set, indicates that a PLL fault occurred where the PLL lost lock. Set the PLLACK bit (see Table 51) in
the start ADC measurement SFR (ADCGO, Address 0xD8) to acknowledge the fault and clear the
PLL_FLT bit.
