Hi, Continuous SCK is enabled by setting the CONT_SCKE bit in the MCR. Continuous SCK is only supported for CPHA=1.

Please pay attention to section 49.4.5 Continuous Serial Communications Clock:

Hello，

Thank you for your answer, I have been able to send data continuously. But I just need to use CPHA = 1 continuous sending operation, is there any other way?
