Hello Community

 

About pin config of i.mx6, I have two questions.

 

Q1:

Only pad that used for input can have pull-up resistor, pad that used for output cannot have pull-up resister.

Is it right? why?

 

Q2:

For Pad Control Register(e.g. IOMUXC_SW_PAD_CTL_PAD_CSI0_DATA18),what does Keeper Enabled mean?

What is Keeper?
