Hi,

This KBA:

https://www.cypress.com/comment/390351

states that there is double buffering with the serial interface.

Is there any further documentation on how this works? Is there an app-note with an according firmware where I can take suggestions for my own firmware?

I only have found examples where writing a byte in the outbuf just sends one byte and you have to check the sent status before sending the next byte, or examples where you have to start the reading of one byte every time and have to move the transferred byte before the next byte can be read.

Best Regards,

Frank
