The voltage/temperature channel ADC control MMR is a 16-bit register that is used to configure the V/T-ADC.
When enabling/disabling the voltage/temperature ADC, the voltage attenuator must also be enabled/disabled via
HVCFG1[7].

Description
Voltage/Temperature Channel ADC Enable.
Set to 1 by user code to enable the V/T-ADC. When enabling/disabling the voltage channel, the voltage attenuator must
Clearing this bit to 0 powers down the V/T-ADC.
VTEMP Current Source Enable.
00 = current sources off.
01 = enables 50 μA current source on VTEMP.
10 = enables 50 μA current source on GND_SW.
11 = enables 50 μA current source on both VTEMP and GND_SW.
Not Used. These bits are reserved for future functionality and should not be modified by user code.
Voltage/Temperature Channel ADC Output Coding.
Set to 1 by user code to configure V/T-ADC output coding as unipolar.
Cleared to 0 by user code to configure V/T-ADC output coding as twos complement.
Not Used. This bit is reserved for future functionality and should be written as 0 by user code.
Voltage/Temperature Channel ADC Input Select.
00 = VBAT/24, AGND. VBAT attenuator selected.
01 = VTEMP, GND_SW. External temperature input selected, conversion result written to ADC2DAT.
10 = internal sensor. Internal temperature sensor input selected, conversion result written to ADC2DAT. The temperature
11 = internal short. Shorted input.
Voltage/Temperature Channel ADC Reference Select.
00 = internal, 1.2 V precision reference selected.
01 = external reference inputs (VREF, GND_SW) selected.
10 = external reference inputs divided-by-two (VREF, GND_SW)/2 selected. This allows an external reference up to
11 = (REG_AVDD, AGND)/2 selected for the voltage channel. (REG_AVDD, GND_SW)/2 selected for the temperature
Not Used. These bits are reserved for future functionality and should not be written as 0 by user code.
