38. Analog Comparator Controller (ACC)
38.1
38.2
6500C–ATARM–8-Feb-11
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.
Refer to
• One analog comparator
• High speed option vs. low power option
• Selectable input hysteresis:
• Minus input selection:
• Plus input selection:
• output selection:
• Interrupt on:
– 0, 20 mV, 50 mV
– DAC outputs
– Temperature Sensor
– ADVREF
– AD0 to AD3 ADC channels
– All analog inputs
– Internal signal
– external pin
– selectable inverter
– Rising edge, Falling edge, toggle
