Bit 1 – ENABLE Global Enable

This bit controls whether the AC is enabled.

Note: Each comparator must also be enabled individually by the Enable (ENABLE) bit in the Comparator n Comparator Control A register (COMP[n].COMPCTRLA).

Value	Description
0	The AC is or being disabled
1	The AC is or being enabled

Bit 0 – SWRST Software Reset

Writing a ‘0’ to this bit has no effect.

Writing a ‘1’ to this bit resets all registers in the AC to their initial state, and the AC will be disabled.

This bit will always read as ‘0’.

Note: Writing a ‘1’ to CTRLA.SWRST will always take precedence, meaning that all other writes in the same write-operation will be discarded.
