The ADC may be configured for 8- or 12-bit result, reducing the minimum conversion time (prop-
agation delay) from 0.5 µs for 12-bit to 3.7 µs for 8-bit result.
ADC conversion results are provided left- or right adjusted with optional ‘1’ or ‘0’ 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.
