From Datasheet IMX8DXAEC Rev2:
"Keeper Circuit Resistance" is defined only single-voltage GPIO port.
But, It seems that we can select bus-keeper setting on following balls via PULL field in pad configuration register.
Q1. Which balls support bus-keeper function? Is it only support above balls?
Q2. The bus-keeper feature is only applied for GPIO input mode. Is it right?
Q3. The bus-keeper feature does not mentioned in the current RM. Will it be revised in the nearly future?
