In this link,SPI Slave SCLK Frequency limited 11.4MHz or 7.2MHz.

But it's 40MHz in the datasheet.

Which one is right?

Hi Paul,

Sorry for my late reply.

Your question made a good point. The datasheet shall prevail. We will update clock limitation in [SPI Slave Driver][https://docs.espressif.com/projects/esp ... slave.html] to 40 MHz.

Hope it helps. If you have other questions, please do not hesitate to contact us. It is recommended to use Provide feedback about this document at the end of each ESP-IDF document.
