Figure 28-1. ADC Overview
The ADC may be configured for 8- or 12-bit result, reducing the 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 eases calculation when the result is represented as
a signed.
PORTA has one ADC. Notation of this peripheral is ADCA.
