I want to interface a CODEC IC to a DSP's SPORT port using the "DSP Mode". However, I run into a problem:
- On the transmit side, the CODEC basically sends one LRCLK clock (8kHz, for example) for the Left and Right Channels (see the attached document)
- On the receive side, the DSP seems to expect one LRCLK clock for the Left Channel, and another LRCLK clock for the Right Channel. The diagram shows that 1 frame consists of 2 LRCLK clock pulses.
How can it possibly work? Is there a way to configure the CODEC and/or DSP so that I can use "DSP Mode" with 8kHz sampling rate and 16 bit for each channel?
Thank you in advance!
