## Serial trace commands

Some ARM-based devices implement a serial trace output using the SWO pin. This is available only when using th SWD interface, and it uses the JTAG TDO pin on the tool to sample the signal. This section describes how to configure the tool for capturing serial trace and how to read the captured serial trace data out of the tool.

Note that the hardware tool performs only raw data capture, storage and forwarding.

All serial trace commands use vendor command 7 (0x87)
