The Analog Comparator Interface (ACIFB) is able to control a number of Analog Comparators
(AC) with identical behavior. An Analog Comparator compares two voltages and gives a com-
pare output depending on this comparison.
The ACIFB can be configured in normal mode using each comparator independently or in win-
dow mode using defined comparator pairs to observe a window.
The number of channels implemented is device specific. Refer to the Module Configuration sec-
tion at the end of this chapter for details.
