The ADC may be configured for 8- or 12-bit result, reducing the minimum conversion time (prop-

agation delay) from 5.0µs for 12-bit to 3.6µs 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.
