11.5
The A/D module can operate during Sleep mode. This
requires that the A/D clock source be set to RC
(ADCS1:ADCS0 = 11). When the RC clock source is
selected, the A/D module waits one instruction cycle
before starting the conversion. This allows the SLEEP
instruction to be executed which eliminates all digital
switching noise from the conversion. When the conver-
sion is completed, the GO/DONE bit will be cleared and
the result loaded into the ADRES register. If the A/D
interrupt is enabled, the device will wake-up from
Sleep. If the A/D interrupt is not enabled, the A/D mod-
ule will then be turned off, although the ADON bit will
remain set.
When the A/D clock source is another clock option (not
RC), a SLEEP instruction will cause the present conver-
sion to be aborted and the A/D module to be turned off,
though the ADON bit will remain set.
Turning off the A/D places the A/D module in its lowest
current consumption state.

A device Reset forces all registers to their Reset state.
This forces the A/D module to be turned off and any
conversion is aborted. All A/D input pins are configured
as analog inputs.
The value that is in the ADRESH:ADRESL registers is
not
ADRESH:ADRESL registers will contain unknown data
after a Power-on Reset.

Effects of a Reset
For the A/D module to operate in Sleep,
the A/D clock source must be set to RC
(ADCS1:ADCS0 = 11). To allow the con-
version to occur during Sleep, ensure the
SLEEP instruction immediately follows the
instruction that sets the GO/DONE bit.
