Forum Post: [Urgent] Bus holder behavior

Hi,

Please let me confirm the following question.

[Question]

What pull-down resister values should we use  for the pin which has bus holder function in order to change the status from "H" to "L" in view of variation of device?

I know that the datasheet has this specification as below.

Regarding to this, we should be mount the pull-down register which can flow the 1.3mA@3.3V.

However. XF pin did not change the status even though mounted this register.  As a result, we could the status by using 1.5kohms (Approximately 2.0mA).

So, I would like to know the best pull-down resistor value which can have a effect of changing the status in view of variation of device.

If you have any questions, please let me know.

Best regards

Kaka
