— TOSC/2 + TCY —

— 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 5.0V, 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.

2: See Section 12.3 “A/D Acquisition Requirements” for minimum conditions.
