TPS65983: Monotonic edge requirements for GPIO signals?

Ronnie Hughes

Part Number: TPS65983

I'm wanting to know whether the TPS65983 GPIO requires monotonic edge signal integrity. I would assume the requirement would be the same as the TPS65982.

 

I attached two scope shots of what I observe right now. Can the port controller GPIO handle these type of edges?

On Apex Creek, this signal is driven directly by Alpine Ridge and it does not have any series termination, nor are the trace length to each port controller length matched.
