LAUNCHXL-CC26X2R1: I2S Multi-Channel support

Part Number: LAUNCHXL-CC26X2R1

Hi

Regarding I2S Driver API, it looks like that it can support 8 channels.

But we check the SYSCFG, it only can set D0 & D1 channels.

Do you know how many channels CC26x2 can support on CC26x2?

Thanks.

    Hi Trevor,

    The answer to your question is in the Technical Reference Manual of the device in sections 24.4.4 - 24.4.7. Actually, I2S, LJF and RJF format are dual mode formats. It means you can use one or two channels with these formats. The DSP format is a single mode format, it means you can use from 1 to 8 channels.

    That being said, I want to be sure you are not confusing "channels" and "data lines". All the formats support maximum 2 data lines.A data line is a physical input or output on a pin.

    I hope this will help,

    Regards,
