Hi
I was wondering if it is possible to use the RT1064 GPIO to synchronously trigger external counters instead of using pin fanout or a 1-to-4 clock buffer.
What would be the output-to-output skew between GPIO output pins controlled by the same DR?
Thank you.

Hi @ccrsa ,
If the two GPIOs are in same group, there will be no difference because you can toggle them in a same register at same time. There isn't hardware path difference for them.

Hi @ccrsa ,
I'm not very clearly understand your requirement. But I think you can use the RT1060 XBAR function.

Thank you for responding @jingpan.
Sorry if I was not clear. What I meant was if you toggled 2 x GPIO outputs from low to high and compared the signal transitions with an oscilloscope, would there be a significant time delay or skew between them and would it be deterministic?
