The pin’s “smart” pull-up shuts off while the pin is forced low. This is done to reduce the standby and
shut-down current.
The QFN package has a contact on the bottom of the package. This contact is conductively connected to
the die substrate, and therefore should be unconnected or connected to the same ground as the device’s
