New! DMA simulation for LPC17xx

Hi,

I am trying to run the DMA example code for LPC17xx from keil using MDK-4. But when I do single step, whenever the instructions related to DMA peripheral register write (or read) is executed, I receive "no write permission" error. I have checked that this behavior is consistent over all the DMA related example codes from any source provider. Instructions for writing other peripheral registers are working fine.

I understand that MDK-4 doesn't support simulation of the DMA. Is this the reason for my observation? Correct me if I am wrong but I believe "no simulation support"
doesn't mean that the address space is restricted memory area.

Please guide me possible cause of my observation.

Thanks
Niraj.
