I know this is a daft question, but I can’t find the answer in the documentation…
Using Design Studio, it is possible to carry commands (AT etc) and well as debug (trace) over a single UART. Clearly a mux is used in the process somewhere. When the UART is initialised, presumably there is an option to enable this mux option and also set data rate.
Can someone point me at a description of this whole serial set-up. I need to implement MODBUS using the UART and require a good understanding of what is going on here.
