      Number of compare (CC) registers available.

      On nRF53 these registers can also be used for capture.

  # If enabled, overflow different than full range (24 bits) is handled
  # through PPI channel which ensures precise timing. If disabled then
  # counter is cleared in the interrupt which results in accumulative error
  # of counter period if top value is different than maximal.

  # If enabled then counter based on nRF RTC peripheral supports only maximal
  # top value. That results in code optimizations and availability of one more
  # channel
