16.7.7.2 Asynchronous Mode

The TPIU is configured in asynchronous mode, trace data are output using the single TRACESWO pin. The TRACESWO signal is multiplexed with the TDO signal. As a consequence, asynchronous trace mode is only available when the Serial Wire Debug mode is selected.

Two encoding formats are available for the single pin output:

Manchester encoded stream. This is the reset value.
NRZ_based UART byte structure
