Table 104. ADC Control Register 0 (ADCCT0)
A user can perform calibration and store the values into Flash, or the user code can per-
form a manual offset calibration. There is no provision for manual gain calibration.
The ADC Control Register 0 initiates the A/D conversion and provides ADC status infor-
mation. See Table 104.
