GPIODx: GPIOx direction
The GPIODx is used to set the direction of GPIOx if it is used as a regular input/output pin (GPx).
0 = GPIOx is an input pin
1 = GPIOx is an output pin
GPIO Data Output Register (GPIO_DATAOUT)
GPIODOx: GPIO output corresponding to bit x
If the GPIOx is used as a general-purpose output pin, then the corresponding GPIODOx
specifies the value to output from this pin.
