Question: SPORT, TDM and DMA

Hi,

In a design based on 21489, I have I2S on 6 of the 8 SPORTs (2 inputs, 4 outputs), and 8-channel TDM on the 2 SPORTs left (1 in and 1 out). What is the best way to set up DMA? In the example code for the 21479/21489 EZKit, the number of channels on all the SPORTs are the same.

Thanks
