Instruction Set of 8086 Microprocessor. These instructions transfer execution control to specified address. Cal, jump, return and interrupt Instruction Set of 8086 Microprocessor. This <b>instruction copies data from a port to AL or AX register. <b> If an 8 bit port is read, the data will go into AL. 8086 microprocessor is a 16 bit microprocessor i.e. its mostly operations are designed to work with 16 bit binary words. PIN DIAGRAM of 8086 MOV AX, [BP+SI]. • Instruction Set - 8086 has 9 instruction (mostly same as in 8085) which are: 1. Data Copy/Transfer instructions. Encoding of 8086 Instructions. 8086 Instruction Encoding-1. Instruction Format (Cont'd) ! Instruction may also be optionally preceded by one or more. When the s bit is set it means that the single byte operand should be sign-extended to 16 bits. The 8086 introduced a new instruction set, but code for an 8080, 8085 or Z-80 could easily be ported to the 8086. The most important new feature of the 8086 was its 16-bit internal registers, which allowed it to address a full 1 MB of RAM. Its 8-bit predecessors could address just 64 KB.
