Microprocessor 8086 Instruction Sets - Learn Microprocessor in simple and easy steps starting from INC ? Used to increment the provided byte/word by 1. 8086 instructions Page 1 of 53 Complete 8086 instruction set Quick reference: Here is an example that uses PRINTN macro: include 'emu8086.inc' ORG 100h21 Dec 2015 Data Transfer Instructions : The MOV instruction is used to transfer a byte or a word of data from a source operand to a destination operand. These operands can be internal registers of the 8086 and storage locations in memory. Register Reg 16 MOV ES, CX Seg. INC, REG memory, Increment. Algorithm: operand = operand + 1. Example: MOV AL, 4 INC AL ; AL = 5 RET. FE /0, INC r/m8, Increment r/m byte by 1. This instruction allows a loop counter to be updated without disturbing the CF flag. Virtual-8086 Mode Exceptions otherwise emulator will step through each instruction of a macro. Here is an example that uses PRINTN macro: include 'emu8086.inc'. ORG 100h. MOV AL, 1. The MOV instruction is the most important command in the 8086 because it .. Rather than use an ADD to increment a register or memory location, the INC When 8086 executes the near CALL instruction it decrements .. INC AX. ;After this instruction AX = 8000h. INC BL. ; Add 1 to the contents of BL register. INC CL. The INC instruction adds one to the destination operand, while preserving the state of the carry flag CF: The destination operand can be a register or a memory Opcode, Instruction, Op/En, 64-Bit Mode, Compat/Leg Mode, Description. FE /0, INC r/m8, M, Valid, Valid, Increment r/m byte by 1. REX + FE /0, INC r/m8*, M
