PWM through DMA on ADSP-21479

Hello,

 

I have a signal that consists of a number of samples. I want to output these through PWM, using a PWM period of 200 ns (5 MHz). This cannot be realised using the PWM core interrupt, since the ISR takes too long. So, I was wondering whether it is possible to do this using DMA, but I cannot find anything in the HRM. Does anyone have an idea/suggestion?

 

Thanks in advance for your support.

 

Kind regards,

Marc
