If the A/D clock source is selected

as RC, a time of TCY is added

before the A/D clock starts. This

allows the SLEEP instruction to be

executed.

These parameters are characterized but not tested.

† Data in ‘Typ’ column is at VIN =12V (VDD = 5V), +25°C unless otherwise stated. These parameters are for

design guidance only and are not tested.

Note 1: ADRESH and ADRESL registers may be read on the following TCY cycle.
