ADC clarification

Projects Programming
1

The Atmega4809 documents refers to ADC'n', but all code examples use only ADC0. Same with third party codes.

I assume '0' refers to the single converter on these boards, but there could be configurations with additional converters --- thus ADC1, ADC2, etc.

Is my understanding correct?

thx

Can you post a link please?

    Shows the 4809 has a single adc that is multiplexed to several pins as shown on the nano every pin out.

In several Microchip docs. I suspect they are just being generic.

I think it is.

You can compare it with the USART. The generic reference is USARTn, the specific reference is e.g. USART0 for the USART0 registers.

Yup.
I found that ATtiny1614 and family have a second ADC.
