[ DS90UB914A-Q1 ] Not to use GPIO

Hi Expert,

It seems that there are no pull-up/down resistors in GPIO[1:0] and GPIO[3:2] pins. If we don't use these pins, can these be left open?

* No GPIO function used between 913A and 914A
* No multiple camera frame sync
* No external reference clock usage
* No BIST

It's great help if you can let me know other things I need to take care.

Thanks,
Ken

Hi Ken,

Correct, these can be left open.

Hi Sean, Liam,

Thank you for following up this .
Quick confirmation, do these GPIO[1:0] GPIO[3:2] pins have internal pull-up/down resistor?

Thanks,
Ken

Hi Ken,

Yes, these are pulldowns however they are very weak. On the order of 6.6 MOhm.
