Note:

Low power modes

The A/D converter may be disabled by resetting the ADON bit. This feature allows reduced

power consumption when no conversion is needed and between single shot conversions.

Description

Wait No effect on A/D converter

A/D converter disabled

Halt After wake-up from halt mode, the A/D converter requires a stabilization time tSTAB (see

Electrical characteristics) before accurate conversions can be performed.
