Can STM32F105 do 13-bit SPI with 13 clocks?

[HForr.1]

I need to interface with a Viniculum II from FTDI. It requires 13 bits over exactly 13 clocks, per this app note. We're using the STM32F105 with HAL libraries from STM32CubeMX. I don't see the cube able to configure to 13 clocks. Will the STM32F105 hardware be able to do only 13 clocks, if I hack the HAL library or write my own? Or is the hardware not able to do 13 clocks?

No

Perhaps in a group, say 13 x8, ie 13 8-bit bytes or 8 13-bit words

Thanks. Now I'll look into the Viniculum II. It might be d*mb sh*t firmware programming at 13 bits, because the hardware itself seems to handle 8-bit words. It does add some status info and I'll have to check, but it's 12, not 13. Finally, the VNC2 timing diagrams include MISO and MOSI and #CS, but not CLK. Who's idea was that? FTDI reputation was the top 20-30 years ago. Today? I'm wondering...

You can always bit-bang it.

ST's designs for SPI have always been a bit simplistic and limited, other platforms have width setting span useful ranges like 5 to 32, and byte counts for CS pins..
