Description
Voltage Channel ADC Enable
This bit is set to 1 by user code to enable the V-ADC. When enabling/disabling the Voltage ADC, the Voltage Attenuator
must also be enabled/disabled via HVCFG1[7].
Clearing this bit to 0, powers down the V-ADC.
Not Used
These bits are reserved for future functionality and should not be modified by user code
Voltage Channel ADC Output Coding
This bit is set to 1 by user code to configure V-ADC output coding as unipolar
This bit is cleared to 0 by user code to configure V-ADC output coding as 2’s compliment
Not Used
This bit is reserved for future functionality and should be written as 0 by user code

Read/Write
The Voltage Channel ADC Control MMR is an 16-bit register that is used to configure the V-ADC.
When enabling/disabling the Voltage ADC, the Voltage Attenuator must also be enabled/disabled via HVCFG1[7].
