| 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. | |
