The ADC may be configured for 8- or 12-bit result, reducing the minimum conversion time (propagation delay) from
3.35µs for 12-bit to 2.3µs for 8-bit result.
ADC conversion results are provided left- or right adjusted with optional â1â or â0â padding. This eases calculation when
the result is represented as a signed integer (signed 16-bit number).
PORTA has one ADC. Notation of this peripheral is ADCA.
