Read/write
The voltage/temperature channel ADC control MMR is a 16-bit register that is used to configure the V-/T-ADC.
If the VBAT attenuator input is selected, the voltage attenuator buffers are automatically enabled.
Description
Voltage/temperature channel ADC enable.
Set to 1 by user code to enable the V-/T-ADC.
Clearing this bit to 0 powers down the V-/T-ADC.
VTEMP current source enable.
00 = disables current sources.
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 attenuator (VBAT/24 and AGND) is selected. The high voltage buffers are enabled automatically in this
configuration. The conversion result is written to ADC1DAT.
01 = external temperature inputs (VTEMP and GND_SW) are selected. The conversion result is written to ADC2DAT.
10 = internal sensor is selected. 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 is selected. Shorted input. The conversion result is written to ADC1DAT.
Voltage/temperature channel ADC reference select.
00 = internal 1.2 V precision reference is selected.
01 = external reference inputs VREF and GND_SW are selected.
10 = external reference inputs divided by 2 (that is, VREF and GND_SW divided by 2) are selected. This allows an external
reference up to REG_AVDD.
11 = the reference input REG_AVDD and AGND divided by 2 are selected for the voltage channel.
The reference inputs REG_AVDD and GND_SW divided by 2 are selected for the temperature channel.
Not used. These bits are reserved for future functionality and should not be written as 0 by user code.
