0013 description:
0014 The MTU2 is a multi-purpose, multi-channel timer/counter with configurable clock inputs
0015 and programmable compare match.
0016
0017 Channels share hardware resources but their counter and compare match value are
0018 independent. The MTU2 hardware supports five channels indexed from 0 to 4.
