Table 36: Debug Connector Interface - Revision 1 and 2 Modules
The trace signals can be used to debug the processor running at full speed, allowing the user to collect
information on the CPU instruction execution and data transfers.
In order to enable the trace interface, TRACE_EN# signal must be pulled low from the debug connector, and
MIO pins 0-9 must be assigned to TRACE controller in the PS settings of the Vivado project. Additionally,
starting with revision 2 modules, the trace clock multiplexer must be equipped. Refer to the XU1
SoC Module User Schematics [6] for details.
