A/D Operation During Sleep
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 internal digital switching noise from the conversion. When the conversion 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 module 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 conversion 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.
Note:
For the A/D module to operate in SLEEP, the A/D clock source must be set to RC
(ADCS1:ADCS0 = 11). To perform an A/D conversion in SLEEP, the GO/DONE bit
must be set, followed by the SLEEP instruction.
