Hi.

I have been made SPI's slave operation but I found a problem.

I have to match slave's output to master's clock but I could not make it.

(I want to make slave's output as red color)

As I Know, there are 2 bits to shift slave's output(to the left or to the right) : Phase, Clock polarity

I set these 2 bits as 4 variants but I could not match.

How can I match the slave's output to the master's clock as above?

Kim.
