DMA - Pheriperal to Memory max Speed

Hi,

 

I'm using a STM32F429 operating at 168 MHz. I want to read in 16 GPIO pins (one port) via DMA. I'm curious what's the maximum input rate is, for a certain number of consecutive level changes (read out of an external ADC).

 

Has anyone an idea? I couldn't find anything in the reference manual.
