The procedure says Set DI and CS high and apply 74 or more clock pulses to SCLK but when try to send some 0xff to get the clock pulses the cs turn low.

Hello, my name is Pavel, and I will be supporting your case, I reviewed your information, but I believe the CS behavior that you mentioned is right, when a transmission starts the CS or "Chip Select" goes down to notify the receiver.

Let me know if you have another related question.

Best regards,
Pavel
