On the following cycle of the device clock.
See Section 19.0 “10-Bit Analog-to-Digital Converter (A/D) Module” for minimum conditions when input

(1)
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.
