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.

ADC value in this register is updated when an ADC interrupt occurs.
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.
