Hi Elber,

you need to activate the "3-phase mode" which is descibed for I2C or something, 
but works for SPI as well. 

Then you can read/write at the other clock edge.

Hello, Stefan,

I also met the problem of the mode limitation in d2xx programming, the
device I use is FT2232, and I need the SPI could be run under the mode of
CPOL = 0 and CPHA =1, until now I still did not find a way to figure it out.

Have you found some solution for the problem?

Thank you so much for your consideration.

Best Regards,

Elber
