7.3
The A/D converter module can operate during Sleep.
This requires the A/D clock source to be set to the
internal RC oscillator. When the RC clock source is
selected, the A/D waits one instruction before starting
the conversion. This allows the SLEEP instruction to be
executed, thus eliminating much of the switching noise
from the conversion. When the conversion is complete,
the GO/DONE bit is cleared, and the result is loaded
into the ADRESH:ADRESL registers. If the A/D
interrupt is enabled, the device awakens from Sleep. If
the A/D interrupt is not enabled, the A/D module is
turned off, although the ADON bit remains set.

’. Shaded cells are not used for A/D converter module.
When the A/D clock source is something other than
RC, a SLEEP instruction causes the present conversion
to be aborted, and the A/D module is turned off. The
ADON bit remains set.
7.4
A device Reset forces all registers to their Reset state.
Thus the A/D module is turned off and any pending
conversion
registers are unchanged.
