Help with SPI and I2C standards

[eng_boody]

hi people how are you,
hope you are fine

I'd like to ask you where Could I get Documents describing the Standards of SPI and I2C like
Commands on binary level , protocol in general , when a master sends a message to slave and
expects a reply what's the delay for response after the last master's bit is send , Registers and how to set ...etc.

the tutorials on the internet i have seen so far explain the principles without going deep into that standards details ..

thanks

You could get precise information on specific devices datasheets rather than at generic tutorials. Moreover, you will note that in general SPI data frame formats varies from a device to another more than if compared to the same kind of function that uses I2C protocol.
