LPC4370 M2M DMA Transfer Speed

Hi,

 

I am using the GPDMA to transfer a block of data out via a GPIO port and I'm trying, with no success, to discover the theoretical frequency at which this should occur based on the system core frequency.

 

I have measured the transfer using a scope at a core frequency of 204MHz and 120MHz. I get a sensible looking answer on the scope given the ration between the 2, however it would really help to discover the actual speed and tolerance.

 

Thanks.
