RHFLVDS2281 internal enable pullup resistor

The RHFLVDS2281 datasheet suggests there is an internal pullup on the EN pin, but doesn't list this value. Does anyone know what this internal pullup resistance is?

    Welcome, @BOver.3​, to the community!

    Well, since no value is given for the pull-up, one can derive its magnitude from the input current of pin EN. The data sheet states in table 7 a maximum of 10µA at VCC=3.6V, so that the effective resistance is ≥360kohms.

    Does it answer your question?
