DMA with eTimer and GPIO

Hi 

I'm using the SPC560P40L1

Im trying to switch a GPIO using pre-defined data stored in memory. I would like the GPIO to switch after a rising edge on a PWM pin which is being monitored by ETC/eTimer. I also need the DMA to control all of this. The CPU is pretty loaded already. 

Is there an example code I could use? Im using the SPC5studio and they only have examples of DMA use with SPI and ADC. 

I looked at the reference manual and that is not easy to start of with as a beginner to DMA  

Can anyone point me in the right direction to get started?

 

-Thanks
