Most of the displays both LVDS and RGB that I have seen have a very stringent requirement that display signals and function signals need to high impedance or low in order to avoid internal circuit damage in the displays. Is there a way this can be ensured by programming the IMX6 processor to keep these line low or high impedance. Otherwise I need to provide an external buffers. I don't see this kind on design implementation on any Freescale boards.
Processor does not perform special actions for these display signals, that is at power up
they are inputs (100K impedance pull or keeper). Power up pads state one can find in Datasheet
section "Package Information and Contact Assignments".
I understand that part of it. I was more looking into some control register setting for the Display IOs that does this job.
Hi Raj
if you are speaking about i.MX6, it has not speical Display module settings
for settings IOs low at power-up. One can set them later after power-up.
