Any serial interface using GPIF II examples?
In multiple places it is mentioned that both parallel and serial interfaces are implemented with GPIF II, but I can't find any examples of a serial interface. I have an I2S like interface which has a bit clock, word clock, and 2 data lines where the rate is 10.4MHz. I'm having trouble figuring out how to configure the GPIF for this. Do I use all GPIO? If so, how do I accumulate the data bits into words and use the DMA buffers? Thanks for your help.
