A logical OR operation is performed between the byte at the memory address specified by the contents of the HL register pair and the contents of the Accumulator, the result is stored in the Accumulator.
| S | is set if result is negative, otherwise it is reset. |
| Z | is set if result is 0, otherwise it is reset. |
| H | is reset. |
| P/V | is reset if overflow, otherwise it is reset |
| N | is reset. |
| C | is reset. |
If the Accumulator contains $12 (0001 0010), register pair HL contains $2323, and memory location $2323 contains byte $48 (0100 1000), then upon the execution of
OR (HL)
the Accumulator contains $5A (0101 1010).
