Hi 

I'm looking for AMR characteristisc for GPIO pins of IMX6Q.

 

Particularity I'm interested how much current can GPIO output  absorb. 

 

I connected the output of GPIO through resistor to another output P1, so that of P1 forces voltage it "wins" , if P1 is HighZ then GPIO forces the line. 

if P1 forces 3.3v but GPIO pulls to 0v then GPIO takeas current of 3.3V/R , what is the allowable current?

 

Bar.
