23.2.4 ADC OPERATION DURING SLEEP
The ADC module can operate during Sleep. This
requires the ADC clock source to be set to the FRC
option. When the FRC oscillator source is selected, the
ADC waits one additional instruction before starting the
conversion. This allows the SLEEP instruction to be
executed, which can reduce system noise during the
conversion. If the ADC interrupt is enabled, the device
will wake-up from Sleep when the conversion
completes. If the ADC interrupt is disabled, the ADC
module is turned off after the conversion completes,
although the ADON bit remains set.
23.2.5
EXTERNAL TRIGGER DURING
SLEEP
If the external trigger is received during sleep while
ADC clock source is set to the FRC, then the ADC
module will perform the conversion and set the ADIF bit
upon completion.
If an external trigger is received when the ADC clock
source is something other than FRC, then the trigger
will be recorded, but the conversion will not begin until
the device exits Sleep.
23.2.6 AUTO-CONVERSION TRIGGER
The Auto-conversion Trigger allows periodic ADC mea-
surements without software intervention. When a rising
edge of the selected source occurs, the ADGO bit is set
by hardware.
The Auto-conversion Trigger source is selected with
the ADACT<4:0> bits of the ADACT register.
