| 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. |
