XMEGA A1 features four Analog Comparators (AC). An Analog Comparator compares two volt-
ages, and the output indicates which input is largest. The Analog Comparator may be configured
to give interrupt requests and/or events upon several different combinations of input change.
Both hysteresis and propagation delays may be adjusted in order to find the optimal operation
for each application.
A wide range of input selection is available, both external pins and several internal signals can
be used.
The Analog Comparators are always grouped in pairs (AC0 and AC1) on each analog port. They
have identical behavior but separate control registers.
Optionally, the state of the comparator is directly available on a pin.
PORTA and PORTB each has one AC pair. Notations are ACA and ACB, respectively.
