Interrupt enable
AIEN enables conversion complete interrupts. When COCO becomes set while the respective AIEN is
high, an interrupt is asserted.

Differential mode enable
DIFF configures the ADC to operate in differential mode. When enabled, this mode automatically selects
from the differential channels, and changes the conversion algorithm and the number of cycles to
complete a conversion.

Input channel select
The ADCH bits form a 5-bit field that selects one of the input channels. The input channel decode
depends on the value of the DIFF bit. DAD0-DAD3 are associated with the input pin pairs DADPx and
DADMx.
The successive approximation converter subsystem is turned off when the channel select bits are all set
(ADCH = 11111). This feature allows for explicit disabling of the ADC and isolation of the input channel
from all sources. Terminating continuous conversions this way prevents an additional single conversion
from being performed. It is not necessary to set the channel select bits to all ones to place the ADC in a
low-power state when continuous conversions are not enabled because the module automatically enters
a low-power state when a conversion completes.
