Is it possible to determine the number of bytes of space remaining in the transmit FIFO on the XMC4500?
Thanks,
Kirk

I answered my own question.
After digging into the reference manual I found:
The Transmit/Receive Buffer Status Register (TRBSR) has bit field Transmit Buffer Filling Level (TBFLVL bits 24:30).
It would be nice if the DAVE UART001App provided access to TBFLVL in its API calls.

Kirk,
have a look at the generated USIC.H.
You will find the macros there.

Yes, thanks, I see the USIC_GetTxFIFOFillingLevel there.
I'm surprised that these macros are not "published" in the API Documentation section of the DAVE3 help for UART001App.
I guess we're just supposed to dig around in the generated code to see what we can find that is useful???
