DMA Usage with CTU and S-RAM (MBD MPC574x)

Dear All

I am trying to use DMA to access the result of an ADC conversion.

I use PWM with 20KHz switching and enable the ADC sampling every 2 PWM cycles and strore the ADc results in CTU FIFO.

I am using DMA Transfer to get the results and pass into SRAM (reg value : 0x40000000 - 0x4005FFFF)

When DMA transfer is complete, I want to read the value from the register.

Question

I can not use read register to read SRAM register values. How can I do this?

I have attached the model.

Best Regards

Abhishek
