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 (Address 0xF4).
A PLL fault is generated if a reset is 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.
