Description
### Description
There are some gaps in the config files for the `cw310` interface which goes through the SAM3X.
* Some pin names are not recognised, leading to errors like `Error: Invalid pin name IOR10`.
* The `dut` UART is not configured correctly, so most UART tests fail.

Research direction
Start by locating the cw310 interface config files and the SAM3X pin-mapping and dut UART entries. Reproduce the invalid IOR10 pin error and the failing UART tests, then update the mappings so the pin is recognised and the dut UART is configured correctly. Done means the reported pin error is gone and the UART tests pass.
