Description
Voltage/temperature channel ADC enable.
Set to 1 by user code to enable the V-/T-ADC.
Cleared to 0 to power 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. The high voltage buffers are enabled automatically in this configuration.
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
gradient is 0.33 mV/°C; this is only applicable to the internal temperature sensor.
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-2 (VREF, GND_SW)/2 selected. This allows an external reference up to REG_AVDD.
11 = (REG_AVDD, AGND)/2 selected for the voltage channel. (REG_AVDD, GND_SW)/2 selected for the temperature channel.
Not used. These bits are reserved for future functionality and should not be written as 0 by user code.
