title: Assembly Tricore load instruction
body: <p>for reference of the assembly language see this <a href="https://www.infineon.com/dgdl/tc_v131_instructionset_v138.pdf?fileId=db3a304412b407950112b409b6dd0352" rel="nofollow noreferrer">link</a></p>
  
  <p>I don't understand what the command</p>
  
  <pre><code>LD.BU      d15,[a15]0x0 
  </code></pre>
  
  <p>exactly does....
  here a specific example:</p>
  
  <pre><code>##What the registers contain BEFORE execution##
  D15    0xD0000894
  A15    0xD0000894
  
  ##What the registers contain AFTER execution##
  D15    0x000000DC
  A15    0xD0000894
  </code></pre>
  
  <p>Can anyone shortly explain me this?</p>
