  13 description:
  14   The MTU2 is a multi-purpose, multi-channel timer/counter with configurable clock inputs
  15   and programmable compare match.
  16
  17   Channels share hardware resources but their counter and compare match value are
  18   independent. The MTU2 hardware supports five channels indexed from 0 to 4.
