| 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. |
