title: Double Carot in Assembly
body: <p>I'm working with some assembly at the moment and I was wondering what the following code meant, specifically the double carot (&lt;&lt;)</p>
  
  <pre><code>.EQU LED0 , 0
  .EQU LED1 , 1
  .EQU LED2 , 2
  .EQU LED3 , 3
  
  ldi R16, (1&lt;&lt;LED0 | 1&lt;&lt;LED1 | 1&lt;&lt;LED2 | 1&lt;&lt;LED3)
  </code></pre>
  
  <p>Is this shifting values somehow? I'm a little confused.
  Note...this is for 8-bit Atmel Instruction Sets. </p>
