     The MCP23017 is capable of converting 16-bit parallel data to serial data of the IIC interface and converting each other. An internal integrated power-on reset (POR) circuit is reset to the device's default state. The two opposites become the interrupt source output. The polarity toggle register configures the GPIO input polarity.
