6.2.3 Register 1 - Output Port register  
This register reflects the outgoing logic levels of the pins defined as outputs by Register 3.  
Bit values in this register have no effect on pins defined as inputs. Reads from this register  
return the value that is in the flip-flop controlling the output selection, not the actual pin  
value.

6.2.4 Register 2 - Polarity Inversion register  
This register allows the user to invert the polarity of the Input Port register data. If a bit in  
this register is set (written with 1), the corresponding Input Port data is inverted. If a bit in  
this register is cleared (written with a 0), the Input Port data polarity is retained.
