Description
ADC Busy Status Bit.
A read-only status bit that is set during a valid ADC conversion or during a calibration cycle.
Busy is automatically cleared by the core at the end of conversion or calibration.
Reserved. This bit should always be written as 0.
Number of Average Selection Bits.
This bit selects the number of ADC readings that are averaged during a calibration cycle.

Reserved. This bit should always be written as 0.
This bit should always be written as 1 by the user when performing calibration.
Calibration Type Select Bit.
This bit selects between offset (zero-scale) and gain (full-scale) calibration.
Set to 0 for offset calibration.
Set to 1 for gain calibration.
Start Calibration Cycle Bit.
When set, this bit starts the selected calibration cycle.
It is automatically cleared when the calibration cycle is completed.
