8.15 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)
    • Internal reference voltage (1.4V, 2.5V)
    • Integrated 8-bit reference DAC, the output can also connect to OPA input terminal internally as an output buffer.
  • Configurable operation modes:
    • High speed mode
    • Lower power mode
  • Programmable output glitch filter delay
  • Supports 6 blanking sources (refer to the CTL2 register of the MSPM0 G-Series 80MHz Microcontrollers Technical Reference Manual)
  • Support output wake up device from most 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.
