GPIO[6:0]: The GPIO bits correspond to GPIO6 through GPIO0, respectively. The function of each bit depends on whether the GPIO pin is configured as an input pin or an output pin, which is determined by the setting in Register 8. When the GPIO pin is configured as an input, reading this register samples the GPIO pin. When the GPIO pin is configured as an output, reading from this register reads back the forced data.
