    Example: ::
        
        from stm.mfx import MFX 
        
        ...
        
        port_expander = mfx.MFX()
        port_expander.pinMode(10,INPUT_PULLUP)
        
        state = port_expander.digitalRead(10)
        
        port_expander.pinMode(0,OUTPUT)
        port_expander.digitalWrite(0,HIGH)
        
        
    
.. method:: pinMode(pin, mode)
    
    Select a mode for a pin.
    Valid *pin* values are from ``0`` to ``15`` included.
