13.3.2. SWO shared with TRACEPORT

A pin can be shared between TRACEDATA[0] and TRACESWO. Because only one of these two pins can be in use at any one time, there is no loss of functionality using this option, and this is the preferred option when a dedicated trace port is present on the package.

To implement this option, the SWOACTIVE output from Cortex-M3 TPIU is used to control the multiplexor. SWO shared with TRACEPORTFigure 13.11 shows the SWO shared with TRACEPORT option.
