Description
If set, indicates that a Rx edge event triggered wake-up from PSM2.
Indicates the power supply that is connected internally to V
V
If set, indicates that V
If set, indicates that PLL is not locked.
If set, the internal voltage reference is enabled in PSM2 mode. This bit should be set if the
LCD is on in PSM2 mode.
This bit should be kept to zero.
Controls the function of the P1.0/RxD pin.

Description
Set this bit to clear the PLL fault bit, PLL_FLT in the PERIPH register. A PLL fault
is generated if a reset was caused because the PLL lost lock.
Reserved.
Set this bit to initiate an external voltage measurement. This bit is cleared
when the measurement request is received by the ADC.
Set this bit to initiate a temperature measurement. This bit is cleared when
the measurement request is received by the ADC.
Set this bit to initiate a battery measurement. This bit is cleared when the
measurement request is received by the ADC.
