Set Settings:Pin Configuration[MFP17_SEL0][MFP17_SEL1][MFP17_SEL2] = 100 to select GPIO (default setting). When this mode is selected, the pin can be used as a general purpose input or output pin. The level of pin is reflected in the data returned by the read-only command GPIORead() (0x48). If the pin is used as an output, then it can be configured as an output driven low, an output driven high or HIGH-Z state by writing to command GPIOWrite() (0x49).
