When the size of the transmit and receive FIFOs are increased the selection of pin assignments decreases.
This is using the XMC45040F100x512 target.

Hi Doug,

Thank you very much for your feedback.
Is it true that the available pin selection list goes wrong when you choose "FIFO size 64" for "Transmit" or "Receive" or both. Actually you should not have the option of "FIFO size 64". The reason is that the total buffer capability is 64 data words shared between receive and transmit FIFO buffers but there is no "FIFO size 0" option available in the drop-down list.
A change request was submitted and we will inform you once it is fixed.

Best regards,
