Forum Post: TMS570LS3137 DMA

Hi

Could you tell me how the DMA HW requests are set in the TMS570LS3137?

I've looked through the TRM but had no luck, though another has been useful though for another TMS570

http://e2e.ti.com/support/microcontrollers/hercules/f/312/t/155766.aspx

 So when I have set

adcREG2->G0DMACR = 0x00000008;

DMAREQ[14] will be called so if I want channel 0 to service this request  I will need

dmaReqAssign(DMA_CH0,14);

is this correct, is the following still correct in the TMS570LS3137?

for a trigger from ADC1_EV

#define MIBADC1_EV_DMA_REQ         7

for ADC2_EV

#define MIBADC2_EV_DMA_REQ        14

Cheers,

Alan
