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.

Set this bit to initiate a supply voltage measurement. This bit will be
cleared when the measurement request is received by the ADC.

TADC
0
Set this bit to initiate a temperature measurement. This bit will be cleared
when the measurement request is received by the ADC.

BATVTH
0
The battery ADC value is compared to this register, the battery threshold
register. If BATADC is lower than the threshold, an interrupt is generated.
