7.3.4 I/Os with Integrated Static Pull-Down Resistors

To help avoid floating inputs on the I/Os, this device has 288kΩ typical integrated weak pull-downs on all data I/Os. This feature allows all inputs to be left floating without the concern for unstable outputs or increased current consumption. This also helps to reduce external component count for applications where not all channels are used or need to be fixed low. If an external pull-up is required, it should be no larger than 30kΩ to avoid contention with the 288kΩ internal pull-down.
