13description:
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.
