Description
Enable start conversion.
This bit is set by the user to start any type of conversion command.
This bit is cleared by the user to disable a start conversion (clearing this bit does not stop the ADC
when continuously converting).
Enable the ADC
This bit is set by the user to enable the ADC
This bit is cleared by the user to disable the ADC
ADC power control.
This bit is set by the user to place the ADC in normal mode (the ADC must be powered up for at least
5 μs before it converts correctly).
This bit is cleared by the user to place the ADC in power-down mode.

When a selected ADC channel is shared with one GPIO, by default, this pin is
configured with a weak pull-up resistor enabled. The pull-up resistor should
be disabled manually in the appropriate GPxPAR register. Note the internal
pull-up resistor on P2.0/AIN12 for 40-lead package cannot be disabled.
