Immediate values
    When you enter an immediate value (constant) in decimal format (for example, -2, 3) the controller stores the value by using 32 bits. If you enter a value in a radix other than decimal, such as binary or hexadecimal, and do not specify all 32 bits, the controller places a zero in the bits that you do not specify (zero-fill).
     IMPORTANT: 
    
Zero-fill of immediate binary, octal or hexadecimal values less than 32 bits.
