AN1043 Unique Features of the MCP23X08/17 GPIO Expanders

The I/O port is highly configurable for maximum flexibility. Figure 1 is a simplified block diagram of an I/O port pin. The port can either drive logic levels on the pin, or read logic levels from the pad. The level on the pad can be read at any time, regardless if the pin is configured as an input .
