Reference Generator
The ADC converts the analog input, ANA
equation for calculating the digital value is represented by:
Assuming zero gain and offset errors, any voltage outside the ADC input limits of AV
and V
software to the ADC control register’s start bit.
Initiating a new conversion, stops any conversion currently in progress and begins a new
conversion. To avoid disrupting a conversion already in progress, the START bit can be
read to determine ADC operation status (busy or available).
