ORL C,BIT . program memory as the first byte of the instruction following AJMP. Example: The label 3.2 Description of all 8051 instructions. EXAMPLE: 8051-chapter-03-image-001 Syntax: ORL A,direct; Bytes: 2 (instruction code, direct byte address); 8051 Instruction Set Manual. Home > Instructions > ORL. ORL. The ORL instruction performs a bitwise logical OR operation on the specified operands, the result MOV - Move Memory; MOVC - Move Code Memory; MOVX - Move Extended Memory; MUL - Multiply Accumulator by B; NOP - No Operation; ORL - Bitwise OR The ORL instruction for byte-size operands has no effect on any of the flags. See Example The 8051 has an instruction for the compare operation. It has the ORL. The ORL instruction performs a bitwise logical OR operation on the specified operands, the result of which is stored in the destination operand. When this instruction is used to modify an output port, the value used as the port data will be read from the output data latch, not the input pins of the port. 8051 Microcontroller Instruction Set.
