AUXADC Measurement Data
Voltage (mV) = AUX_DATA x 1.465
ChipTemp (°C) = (512.18 - AUX_DATA) / 1.0983
BattTemp (°C) = (value is dependent on NTC
thermistor)
AUXADC Enable
0 = Disabled
1 = Enabled
Note - this bit is reset to 0 when the OFF power state is
entered.
AUXADC Conversion Enable
0 = Disabled
1 = Enabled
In automatic mode, conversions are enabled by setting
this bit.
In manual mode (AUX_RATE = 0), setting this bit will
initiate a conversion; the bit is reset at the end of the
conversion.
