I can't find the maximum speed for SCK on SPI in SLAVE mode!!!

Did anyone find info on that?

The May 3, 2004 User Manual says on page 162:

"The following sequence describes how one should process a data 
transfer with the SPI block when it is set up to be a slave. This
process assumes that any prior data transfer has already completed. 
It is required that the system clock driving the SPI logic be
at least 8X faster than the SPI."

So SCK can be at most 1/8 of cclk.
