54. Analog Comparator Controller (ACC)
54.1 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).
54.2 Embedded Characteristics

VOLT_REF Voltage References Selectable for Comparison: External Voltage Reference, DAC0, DAC1,
Temperature Sensor (TS)
• Interrupt Generation
• Compare Event Fault Generation for PWM
