23 Nov 2017 The Mnemonics associated with the Arithmetic Instructions of the 8051 Microcontroller Instruction Set are: ADD. ADDC. SUBB. INC. DEC. MUL. DIV. DA A.
Alphabetical List of Instructions. ACALL - Absolute Call; ADD, ADDC - Add Accumulator (With Carry); AJMP - Absolute Jump; ANL - Bitwise AND; CJNE - Compare and Jump if Not Equal; CLR - Clear Register; CPL - Complement Register; DA - Decimal Adjust; DEC - Decrement Register; DIV - Divide Accumulator by B
The byte specified by the second operand is copied to the location specified by the first operand. The source data byte is not affected. See Also: MOVC, MOVX MOV @Rn, #immediate C AC F0 RS1 RS0 OV P Bytes 2 Cycles 1 Encoding 0111011n immediate Operation MOV (Rn) = immediate Example MOV @R0, #0 MOV
Boolean Variable Instructions. ? The C8051 processor can perform single bit operations. ? The operations include set, clear, and, or and complement instructions. ? Also included are bit–level moves or conditional jump instructions. ? All bit accesses use direct addressing. ? Examples: SETB TR0. ;Start Timer0. POLL: JNB.
8051 Instruction Set. This tutorial includes 8051 microcontroller Instructions set of data moving, branching, arithmetic, logical operations etc. that a 8051 microcontroller makes use of.

12 Apr 2012 8051 instruction set. Microprocessors 1 The 8051 Instruction SetMicroprocessors 1 Msc. Instruction Groups• The 8051 has 255 instructions – Every 8-bit opcode from 00 to FF is used except for A5.• The instructions are grouped into 5 groups – Arithmetic – Logic – Data Transfer – Boolean – BranchingMicroprocessors 1 Msc.
The following table lists the 8051 instructions by HEX code. Hex Code Bytes Mnemonic Operands 00 1 NOP 01 2 AJMP addr11 02 3 LJMP addr16 03 1 RR A 04 1 INC A 05 2 INC direct 06 1 INC @R0 07 1 INC @R1 08 1 INC.
For example: INC R1 - Means: Increment register R1 (increment register R1); LJMP LAB5 - Means: Long Jump LAB5 (long jump to the address marked as LAB5); JNZ LOOP - Means: Jump if Not Zero LOOP (if the number in the accumulator is not 0, jump to the address marked as LOOP);
