Description
Embedded Characteristics
The Analog Comparator Controller configures the Analog Comparator and generates an inter-
rupt according to the user settings. The analog comparator embeds 8 to 1 multiplexers on both
inputs.
The Analog Comparator compares two voltages and the result of this comparison gives a com-
pare output. The user can select a high-speed or low-power option. Additionally, the hysteresis
level, edge detection and polarity are configurable.
The ACC can also generate a compare event which can be used by the PWM.
