Primary ADC Enable
Set

Reserved for Future Use
Primary and Auxiliary ADC Mode bits.
These bits select the operational mode of the enabled ADC as follows:

Idle Mode
In Idle Mode the ADC filter and modulator are held in a reset state
although the modulator clocks are still provided.

Single Conversion Mode
In Single Conversion Mode, a single conversion is performed on the
enabled ADC. On completion of the conversion, the ADC data regis-
ters (ADC0H/M/L and/or ADC1H/L) are updated, the relevant flags
in the ADCSTAT SFR are written, and power-down is re-entered with
the MD2–MD0 accordingly being written to 000.

Continuous Conversion
In continuous conversion mode the ADC data registers are regularly
updated at the selected update rate (see SF register)

NOTES
1. Any change to the MD bits will immediately reset both ADCs. A write to the MD2–0 bits with no change is also treated as a reset. (See exception to this in Note 3 below.)
2. If ADC0CON is written when AD0EN = 1, or if AD0EN is changed from 0 to 1, then both ADCs are also immediately reset. In other words, the Primary ADC is
given priority over the Auxiliary ADC and any change requested on the primary ADC is immediately responded to.
3. On the other hand, if ADC1CON is written or if ADC1EN is changed from 0 to 1, only the Auxiliary ADC is reset. For example, if the Primary ADC is continuously
converting when the Auxiliary ADC change or enable occurs, the primary ADC continues undisturbed. Rather than allow the Auxiliary ADC to operate with a phase
difference from the primary ADC, the Auxiliary ADC will fall into step with the outputs of the primary ADC. The result is that the first conversion time for the
Auxiliary ADC will be delayed up to three outputs while the Auxiliary ADC update rate is synchronized to the Primary ADC.
4. Once ADCMODE has been written with a calibration mode, the RDY0/1 bits (ADCSTAT) are immediately reset and the calibration commences. On completion,
the appropriate calibration registers are written, the relevant bits in ADCSTAT are written, and the MD2–0 bits are reset to 000 to indicate the ADC is back in
power-down mode.
5. Any calibration request of the Auxiliary ADC while the temperature sensor is selected will fail to complete. Although the RDY1 bit will be set at the end of the
calibration cycle, no update of the calibration SFRs will take place and the ERR1 bit will be set.
6. Calibrations are performed at maximum SF (see SF SFR) value guaranteeing optimum calibration operation.
