The ADC_CONTROL register controls some features of the bq76PL536.
[7] not implemented. Must be written as 0.
[6] (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.

[3] (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): These three bits select the series cells for voltage measurement translation on the next
conversion sequence start.
