8.17 COMP

The comparator peripheral in the device compares the voltage levels on two inputs terminals and provides a digital output based on this comparison. It supports the following key features:

  • Programmable hysteresis
  • Programmable reference voltage:
    • External reference voltage (VREF IO)
    • Dedicated Internal reference voltage (1.4V, 2.5V) available in RUN/SLEEP/STOP/STANDBY modes.
    • Integrated 8-bit reference DAC
  • Configurable operation modes:
    • High speed mode
    • Lower power mode
  • Programmable output glitch filter delay
  • Support output wake up device from all low power modes
  • Output connected to advanced timer fault handling mechanism
  • The IPSEL and IMSEL bits in comparator registers can be used to select the comparator channel inputs from device pins or from internal analog modules.
