Overview#

Bitwise OR takes two bit patterns of equal length and performs the 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:

• 0101 (decimal 5) Bitwise OR
• 0011 (decimal 3) =
• 0111 (decimal 7)

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:

• 0010 (decimal 2) Bitwise OR
• 1000 (decimal 8) =
• 1010 (decimal 10)
