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?
Best Regards,
ZongbiaoLiao

Hi Igor
Thank you for you reply.
So there is no relationship between pull-up and the direction of pad.Right?
