39.3 Low-Power Comparator Input Common-Mode Voltage Range Selection

The Low-Power Comparator's input common-mode voltage range can be selected using the CMR bits. This allows for more precise control of the common-mode input ratio. The common-mode range selections include:
  • Rail-to-Rail (VSS to VDD)
  • 1V to VDD
  • VSS to (VDD - 1V)
Important: The CMR bits may only be changed when the comparator is disabled (EN = 0).
