36.5.1 I/O Lines

Each comparator in the AC has multiple I/O pins that can be used as analog inputs or external voltage references. These pins should be configured for analog operation before using them as COMPn inputs.

Each comparator has one or more I/O pins that can be used as digital output. To avoid the pin being tri-stated when COMPn is disabled or in sleep mode, the COMPn-OUT pin must be configured as an output.

Refer to the Pinout and Multiplexing section in the Pinout chapter and the PORT – I/O Pin Controller chapter for details.
