[PIC] problem about communication under CKP=1&CKE=0 in SSP

Zhaoyue Wang
 When I use CKP=0&CKE=0 and without SS (the SCK is drawn to 0 in hardware), the communication is very well.
While I use CKP=0&CKE=0 and without SS (the SCK is drawn to 1 in hardware), the receiver got some wrong data during communication.

I use pic16f877 and the rate of SSP is 5MHz.

can anyone tell me what is the problem?

thx

Norman wang
