44.17.10 Example of configuration

•
Set the bit TRCENA in the Debug Exception and Monitor Control Register (DEMCR)
•
Write the TPIU Current Port Size Register to the desired value (default is 0x1 for a 1-bit
port size)
•
Write TPIU Formatter and Flush Control Register to 0x102 (default value)
•
Write the TPIU Select Pin Protocol to select the synchronous or asynchronous mode.
Example: 0x2 for asynchronous NRZ mode (UART like)
•
Write the DBGMCU control register to 0x20 (bit IO_TRACEN) to assign TRACE I/Os
for asynchronous mode. A TPIU Synchronous packet is emitted at this time
(FF_FF_FF_7F)
• Configure the ITM and write the ITM Stimulus register to output a value
