Bit

Value

Description

Enable start conversion.

This bit is set by the user to start any type of conversion command.

This bit is cleared by the user to disable a start conversion (clearing this bit does not stop the ADC

when continuously converting).

Reserved

ADC power control.

This bit is set by the user to place the ADC in normal mode (the ADC must be powered up for at least

5 μs before it converts correctly).

This bit is cleared by the user to place the ADC in power-down mode.

4 to 3

Conversion mode.

Single-ended mode.

Differential mode.

Reserved.

2 to 0

Conversion type.

000

Enable CONVSTART pin as a conversion input.

001

Enable Timer1 as a conversion input.

010

Enable Timer0 as a conversion input.

011

Single software conversion. This bit is set to 000 after conversion (note that Bit 13 of the ADCCON

MMR should be set before starting a single software conversion to avoid further conversions

triggered by the CONVSTART pin).

100

Continuous software conversion.

101

PLA conversion.

Other

Reserved.

Others

Reserved.

When a selected ADC channel is shared with one GPIO, by default, this pin is

configured with a weak pull-up resistor enabled. The pull-up resistor should

be disabled manually in the appropriate GPxPAR register. Note the internal

pull-up resistor on P2.0/AIN12 for 40-lead package cannot be disabled.
