Question:

Are AVCC0 and AVCC1 connected to each other internally?

Are AVRH0 and AVRH1 connected to each other internally?

What happens if one of those pins is open? 

 

Answer:

AVCC0 and AVCC1 are not connected internally.

AVRH0 and AVRH1 are not connected internally.

If the AVCC pin open, the ADC result is undefined. This may lead to damage to the MCU because of latch up.

If the AVRH pin open, the ADC result is undefined.
