SPI Clock configuration

Hi, Can anyone please let me know what could be the maximum clock frequency that the WizFi250 supports for SPI interface in slave mode and please let me know if I can find a timing diagram for data/instruction transfer using SPI interface on the device.


refer to below URL

It is WizFi250 SPI Speed information.

WizFi250 SPI maximum clock frequency is 2.25Mhz, Effective Rate 500Kbps.

Thank you
