title: MSP430 assembly instructions
body: <p>I am trying to understand what these instructions do for the MSP 430 processor:</p>
  
  <pre><code>(1) MOV.w  #0x0055,R5
  (2)   BIC.w  #0xFFEE,R5
  (3)   BIS.w  #0x1144,R5
  </code></pre>
  
  <p>I haven't been able to find much that explains the assembly instructions and would love to find out what these instructions do and what is stored in the r5 register after each instruction. Could someone explain?</p>
