Hi all

My customer want to minimize power consumption.

Can user reduce the power consumption by changing the register settings of unused pins ?

Do you have any information for it ?

I have already read following application note but can't find a such information.

Hi Ko-hey

seems for unused pins one can only try to change/disable pull resistors

or set it as open drain (bit ODE register IOMUXC_SW_PAD_CTL_PAD_x_y).

Best regards

Hi Igor

Thank you for your quick reply.

Let me confirm the meaning of your following comment.

seems for unused pins one can only try to change/disable pull resistors

What is the meaning of the pull resistors ?

I think that the pull resistor means PKE field.

Is it correct ?
