Bits 5-4: RESERVED: Must Write to 00b.

Bit7
AD0EN: ADC0 Enable Bit.
0: ADC0 Disabled. ADC is in low-power shutdown.
1: ADC0 Enabled. ADC is active and ready to perform calibrations or conversions.
Note: Disabling the ADC automatically resets the AD0SM bits back to the "Idle" state.
Unused: Read = 0b, Write = don’t care.
Unused: Read = 0b, Write = don’t care.
These bits define the operating mode for the ADC. They are used to initiate all ADC conver-
sion and calibration cycles.
000: Idle
001: Full Internal Calibration (offset and gain).
010: Single Conversion.
011: Continuous Conversion.
100: Internal Offset Calibration.
101: Internal Gain Calibration.
110: System Offset Calibration.
111: System Gain Calibration.
Note: Any system mode change by the user during a conversion or calibration will
terminate the operation, and corrupt the result. To write to many of the other ADC reg-
isters, the AD0SM bits must be set to IDLE mode (000b).
