16.7.7.3 How to Configure the TPIU

This example only concerns the asynchronous trace mode.

Set the TRCENA bit to 1 into the Debug Exception and Monitor Register (0xE000EDFC) to enable the use of trace and debug blocks.

1. Write 0x2 into the Selected Pin Protocol Register.
   • Select the Serial Wire output – NRZ
2. Write 0x100 into the Formatter and Flush Control Register.
3. Set the suitable clock prescaler value into the Async Clock Prescaler Register to scale the baud rate of the asynchronous output (this can be done automatically by the debugging tool).
