Hello,

We found that INITX pin has an internal pull-high, and we can't using the BMC(internal 78K-128K PD) control this pin to low level.

Do you know how to disable INITX pull-high of MB9BF368N?  Could we set INITX level to 0?

How to control/design this pin for other customer?

Sorry for late reply.

I'd like to know if you mean the INITX can not be driven as low even though the BMC driving output is low? I don't think the internal pull-up can effect the low level output.

This topic gets any update over last months?

It seems caused by the pull-down resistor in your BCM together with the pull-up resistor of MB9BF368N INITX pin. Maybe the drive mode of BCM controller pin is wrong and the pull-down resistor should not be there. Let me know if you already have get this issue resolved.
