title: Renesas Multi-Function Timer Pulse Unit 2 (MTU2)

description:
  The MTU2 is a multi-purpose, multi-channel timer/counter with configurable clock inputs
  and programmable compare match.

  Channels share hardware resources but their counter and compare match value are
  independent. The MTU2 hardware supports five channels indexed from 0 to 4.
