Problem setting up Trace and ethernet pins in S32K148 ( ETM )

I would like to set up the TPIU pins for trace but i have a problem that the pin PTD11 for Trace Data out 2 is already configured by ENET RMII Transmit Clock.   ( PTC2 pin is also set up for RMII Transmit data 0)

Possible solutions are: either to use less data bits but then its likely/chance to lose data, or i can make both pins available in the PCB and only when programming ENET, i will use less trace data pins.

Any other solution to be able to trace ENET with all the trace 4 data pins ? 

thanks!

Cheers,

Nader

Hello Nader,

Unfortunately, I don't see any other solution, all the pin functions can't be used at at the same time.
