When viewed as a 8-bit value, the contents of the Index register completely specify a single  
internal-register byte. For example, when the value of this register is in the range 00h3Fh, a  
Socket A register is selected (Socket Index bit is 0), and when the value of this register is in the  
range 40h7Fh, a Socket B register is selected (Socket Index bit is 1). This register only reads  
back for Device 0. Device 1 will read back only the upper data byte when 16-bit reads occur at  
3E0h.  
The internal register that is accessed when the CPU reads or writes the Data register is determined  
by the current value of the Index register, as follows:
