Rolf, thank you for your reply. After scouring the FTDI site and elsewhere I think you are correct that it would not be possible using the MPSSE library/controller. I have instead started using the D2XX LabVIEW vi functions and have been sandboxing the synchronous bit-bang mode on my FTDI board HW. It looks fairly straightforward to make a pseudo SPI interface and include the additional sync pulse I need assigned to the next available OP line. I just cant run at the clk rate intended, but for my proof of concept its fine for me at this time.

I have downloaded, configured and got the MPSEE SPI interface LV SW working for my application, thank you. But I also need a single pulse output on a separate IO line, syncronous to the SPI clk. I am unsure how I could configure to cause (for example) the first clk rising edge of any SPI word to trigger the separate pulse from one of the unused lines e.g. the next line above the CS line, AD4? The pulse is reqd to trigger/sync a piece of external equipment and I have the ability on that equipment to delay from the trig pulse, so the PW of the trig pulse is not really important. The important thing is that the timing wrt to the SPI clk is constant. An help gratefully received.
