ESP32 SPI

Hi,
I am using ESP32 with SPI communication and needs ESP32 to be a wifi module which can act as an SPI slave.
The host should be able to send/receive data to/from ESP32.
I did not find slave driver and I tried to write one.
There is very less documentation in TRM (Technical reference manual) related to Slave configuration.
But have a lot of registers to be configured.
Does anybody provide some good documentation related to SPI slave configuration to help me out writing a good SPI slave driver.
Or some one could share a good SPI slave driver.

Thanks in advance.
