The AC is enabled by writing a ‘1’ to the Enable bit in the Control A register (CTRLA.ENABLE). The AC is disabled by writing a ‘0’ to CTRLA.ENABLE. In addition to this AC module enable configuration, AC must also be enabled in the PMD module.

The AC is reset by writing a ‘1’ to the Software Reset bit in the Control A register (CTRLA.SWRST). All registers in the AC are reset to their initial state, and the AC is disabled. See CTRLA register from Related Links.
