Optional Operating Modes: External Voltage Reference Option
D0 and D1 are multi-functional pins with the following functions in different operating modes (see RegMode
register for control settings):
This allows external monitoring of the internal bandgap reference or the ability to use an external reference input
for the ADC, or the option to filter the internal V
The internally generated V
When using an external V
the external value for 1.22 V in the ADC conversion calculations.
