8051 Instruction Set Summary. Rn. Register R7-R0 of the currently selected Register Bank. Data. 8-bit internal data location's address. This could be an internal Data. RAM location (0-127) or a SFR [i.e. I/O port, control register, status register, etc. (128-255)]. @Ri. 8-bit Internal Data RAM location (0-255) addressed indirectly
The 8051 instructions have 8-bit opcodes 28 = 256 instructions. – 255 are implemented and 1 is undefined. Ex2: What is the opcode for the following instruction? – MOV A,R7. – Solution: EFH (=11101111B). 111. 10111 .. DS5000T microcontroller has a RTC. The RTC provides the time of day (Hour:Minute:Second) and

Here you have a compact listing of all 8051 opcodes with links to their detailed description.
A computer instruction is made up of an operation code. (op-code) followed by either zero, one or two bytes of operands. ? The op-code identifies the type of operation to be performed while the operands identify the source and destination of the data. ? The operand can be: ? The data value itself. ? A CPU register.
