Hi community,

 

Our customer have a question about i.MX6UL pin.
Please see Table 95 in IMX6ULCEC Rev.1.
The Out of Reset Condition of many pads are "Input, value=keeper".
Our customer want to know whether external pull-up/pull-down to decide input logic, because thye think i.MX6UL will unexpected work by undifined logic if these pads are floating.
Would you let me know whether should they connect pull-up or pull-down to these pads?
Or external pull-up/pull-down is needed since internal pull-up/pull-down decide the logic?


Best Regards,
