I'm trying to use the codec on the 827EVM board. While I understand the I2S protocol, I'm not clear on how things work on the software side. Since the dsp is interrupt, rather than DMA, driven, if I configure the I2S frame to be 16 words long, and only use 2 words, how many interrupts do I actually recieve? Additionally, is there any indication recieved at the start of a frame? Or to distinguish left and right channel data ?
