title: Assembly Op code question
body: <p>If I am creating an instruction set for an 8-bit computer, is it possible for me to have some instructions with 2 bit op codes and some instructions with 3 bit op codes? The values of each of the op codes will be different, of course.</p>
  
  <p>I have 3 r type instructions that have an op code of 00
  I have 3 i type instructions, with op codes 01,11, and 10
  Could I then make an instruction with an op code 100?</p>
