[[File:0...15 OR.svg|thumb|Bitwise OR of 4-bit integers]]
A '''bitwise OR''' is a [[binary operation]] that takes two bit patterns of equal length and performs the [[Logical disjunction|logical inclusive OR]] operation on each pair of corresponding bits. The result in each position is 0 if both bits are 0, while otherwise the result is 1. For example:

    0'''101''' (decimal 5)
 OR 0'''011''' (decimal 3)
  = 0'''111''' (decimal 7)

The bitwise OR may be used to set to 1 the selected bits of the register described above. For example, the fourth bit of 0010 (decimal 2) may be set by performing a bitwise OR with the pattern with only the fourth bit set:

    '''0'''0'''1'''0 (decimal 2)
 OR '''1'''0'''0'''0 (decimal 8)
  = '''1'''0'''1'''0 (decimal 10)
