Figure 29-1. ADC Overview
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 ‘1’ or ‘0’ padding. This eases calculation when
the result is represented as a signed integer (signed 16-bit number).
PORTA and PORTB each has one ADC. Notation of these peripherals are ADCA and ADCB, respectively.
