The Opcode column gives the complete object code produced for each form of the instruction. When possible, the codes are given as hexadecimal bytes, in the same order in which they appear in memory. Definitions of entries other than hexadecimal bytes are as follows:
|AL = 0||AX = 0||EAX = 0|
|CL = 1||CX = 1||ECX = 1|
|DL = 2||DX = 2||EDX = 2|
|BL = 3||BX = 3||EBX = 3|
|AH = 4||SP = 4||ESP = 4|
|CH = 5||BP = 5||EBP = 5|
|DH = 6||SI = 6||ESI = 6|
|BH = 7||DI = 7||EDI = 7|
