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

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