If set, indicates that an Rx edge event triggered wake-up from PSM2.
If set, indicates that V
If set, indicates that a PLL fault occurred where the PLL lost lock. Set the PLLACK bit (see Table 50) in
the Start ADC Measurement SFR (ADCGO, 0xD8) to acknowledge the fault and clear the PLL_FLT bit.
Set this bit to enable internal voltage reference in PSM2 mode. This bit should be set if LCD is on in
PSM2 mode.
This bit should be kept to zero.
Controls the function of the P1.0/RxD pin.
