TMS570LC4357: DMA rotating priority scheme

Part Number: TMS570LC4357

Hi,

I'd like to know how to set the DMA queue for rotating queue as described in the TRM:

I know that I can set the high/low priority of the channel by writing the CHPRIOS/CHPRIOR regs, but I could not find a way to change the mode from default fixed priority to rotating one.

Regards,

Bartek
