ADC_ON

This bit forces the ADC subsystem ON. This has the effect of

eliminating internal start-up and settling delays, but increases

current consumption.

0 = Auto mode. ADC subsystem is OFF until a conversion is

requested. The ADC is turned on, a wait is applied to allow the

reference to stabilize. Automatically returns to OFF state at end

of requested conversion. Note that there is a start-up delay

associated with turning the ADC to the ON state in this mode.

1 = ADC subsystem is ON, regardless of conversion state.

Power consumption is increased.

5-4

TS[1]..[0]

These two bits select whether any of the temperature sensor

inputs are to be measured on the next conversion sequence

start. Refer to Table 12.

GPAI

This bit enables and disables the GPAI input to be measured on

the next conversion-sequence start.

0 = GPAI is not selected for measurement.

1 = GPAI is selected for measurement.

2-0

CELL_SEL[2]..[0]

These three bits select the series cells for voltage measurement

translation on the next conversion sequence start. Refer to

Table 13.
