title: Is there an x86 opcode for moving an immediate byte to a direct memory location (without using registers)?
body: <p>Is there a way to 'mov'e a specific immediate byte-size number into a direct memory location? I.e.</p>
  
  <pre><code>MOV 10h,ffffh
  </code></pre>
  
  <p>to write the value <code>16</code> into the memory address <code>65535</code>? If so, which opcode is that, orwould I have to store a memory address into a register first?</p>
