EDMA event triggred via GPIO

Other Parts Discussed in Thread: TMS320C6747

Hi there

I'm using TMS320C6747 and  trying to use EDMA with Event triggered

let's assume that an external device(it is connected through GPIO of the TMS320C6747) generates Clock Signal and

the GPIO generates EDMA event to the EDMA at the rising edge of the Clock Signal

and then, EDMA trasnfers 2bytes to the fixed address(from internal memory to external memory)

in other words, EDMA transfer just 2bytes at every single rising edge of the clock

(a transfer request is submitted to the trasnfer controller at every single rising edge )

in this case, what is the maximum frequency of the Clock(external device generates it)?

and

in my case, is there another way to synchronize EDMA operation in rising edge of the clock except the GPIO event?
