General-purpose data. There is a one-to-one correspondence between these bits
and GPIO pins. When a GPIO pin is configured as a general-purpose input, the
value of the pin can be read from this register. When the pin is defined as a
general-purpose output, the value written to this register appears on the GPIO pin.
When one of the GPIO(15:0) pins is configured as other function, the
corresponding bit value in this register is invalid.
