The Internal Voltage Reference Generator provides the voltage, VR2, for the RBUF. 
VR2 is 1.6 V.
You can calibrate and store the values into Flash, or the user code can perform a manual
offset calibration. There is no provision for manual gain calibration.
The ADC Control Registers are described in the following paragraphs.
The ADC Control Register 0 initiates the A/D conversion and provides ADC status
