| description: |
| The CMT is a multi-channel 16/32/48-bit timer/counter with configurable clock |
| inputs and programmable compare match. |
| |
| Channels share hardware resources but their counter and compare match values |
| are independent. A particular CMT instance can implement only a subset of the |
| channels supported by the CMT model. Channel indices represent the hardware |
| position of the channel in the CMT and don't match the channel numbers in the |
| datasheets. |
