41. Analog Comparator Controller (ACC)
41.1 Description
The Analog Comparator Controller (ACC) configures the analog comparator and generates an interrupt depending
on user settings. The analog comparator embeds two 8-to-1 multiplexers that generate two internal inputs. These
inputs are compared, resulting in a compare output. The hysteresis level, edge detection and polarity are
configurable.
The ACC also generates a compare event which can be used by the Pulse Width Modulator (PWM).
Refer to Figure 41-1 on page 1045 for detailed schematics.
