title: Dividing A Register With 16 Bit Into 8 Bit Two Parts
body: <p>i have encountered some registers in some websites and my textbook. Generally, 16 bit registers are divided into two parts. These two parts with 8 bits are classified L(low) and H(high). </p>
  
  <p>Why is this performed ? </p>
  
  <p>Is it that we work on the 8 bit registers ? </p>
  
  <p>Do these low and high specify an input for utilizing different parts of the register ?</p>
