From the two bytes of data output by the device, the value for the register can  
be derived as shown:  
Register value =  
(First Byte * 256) + Second Byte  
The register value is represented in two's compliment in order to provide for  
positive and negative register values.  
The most significant bit of the 16 bit energy register (active or reactive) may be  
used as an indication of the direction of the energy flow (0 = positive, 1 =  
negative).
