Operation During Sleep
Effects of a Reset
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 is 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 (to conserve power),
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.
The value that is in the ADRESH:ADRESL registers is not modified for a Power-on Reset. The
ADRESH:ADRESL registers will contain unknown data after a Power-on Reset.
Note:
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 conversion to occur during SLEEP, ensure the
SLEEP instruction immediately follows the instruction that sets the GO/DONE bit.
