The A/D conversion result never decreases with an increase in the input voltage and has no missing codes.

Maximum allowed impedance is 8.8 kΩ. This requires higher acquisition time than described in the A/D
chapter.

REFH
REFL
If the A/D clock source is selected as RC, a time of T
This allows the SLEEP instruction to be executed.
This is a minimal RC delay (typically 100 ns), which also disconnects the holding capacitor from the analog input.
