The time of the A/D clock period is dependent on the device frequency and the T
ADRES register may be read on the following T
The time for the holding capacitor to acquire the “New” input voltage when the voltage changes full scale
after the conversion (AV
50.
On the following cycle of the device clock.

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.
