... AD0 and AD2 (Tables 2 and 3). For I/O ports used as inputs, ensure that the default states are logic-high so that the I/O ports power up in the high- impedance state. All I/O ports configured with pullups enabled also have a logic-high power-up state. Maxim Integrated 2 C Port Expander with 8 Push-Pull and 8 Open-Drain I/Os INPUT ...
