Hi all,

 

I have a question about recommendation of PMIC_STBY_REQ when it unused.

I'll not use the function of PMIC_STBY_REQ so I want to know the recommendation.

 

I can' find any recommendation about it in hardware design guide for i.MX6SL.

On the other hand, I found a recommendation about it in hardware design guide for i.MX6Q.

It says that If unused, the signal should be left unconnected:

Can i.MX6SL leave it unconnected same as i.MX6Q ?

 

My concern is those signal type is different.

i.MX6Q is open-drain output.

i.MX6SL is push-pull output.
