Hi there,
I am aware that this is an old post, but never is too late I guess...
Actually, CCB is more like a "tiny" version of I2C, in the way that is much simpler and therefore easier to implement. Did you read the Sanyo's CCB bus format datasheet? It tells a lot about how to properly sync the CE, CL and DI/DO signals, format the I/O data, typical compatible (Sanyo) devices address ranges, and other useful stuff like that.
You might also find useful the information contained on the (Sanyo) devices datasheets that use CCB (e.g. the LC75874E LCD driver datasheet has specific case use details).
Finally, as @nelu22 says, I suggest you to take a look into the CCB library implementation kindly developed by Rodolfo Broco Manin.
I really hope you or anyone else finds this information useful, as it's my first post ever here 
Cheers!
