    Also known as:
    
    data mask
    
    masking pattern
    
  

  

  
  
One of eight predefined XOR patterns applied to the data region to avoid problematic module arrangements (large uniform areas, accidental finder-like sequences). The encoder evaluates all eight and selects the best one.
