Analog Comparator startup time =
Each time an AC is enabled, the AC comparison will be enabled after the startup time of the AC.
0: The Analog Comparator outputs feeds the channel logic in ACIFB.
1: The Analog Comparator outputs are bypassed with the AC Test Register.
Writing a zero to this bit has no effect.
Writing a one to this bit starts a comparison and can be used for test purposes.
This bit is cleared when comparison is done.
This bit is set when an enabled peripheral event is received.
Writing a zero to this bit has no effect.
Writing a one to this bit starts a Single Measurement Mode comparison.
This bit is cleared when comparison is done.
0: A peripheral event will not trigger a comparison.
1: Enable comparison triggered by a peripheral event.
0: The ACIFB is disabled.
1: The ACIFB is enabled.
