Intel 8085 Microprocessor Instructions - Hex codes and Mnemonics

In this post, we will see the 8085 Microprocessor instructions and corresponding hex codes. This table is useful to hand assemble the 8085 program. In many universities, 8085 programming is included for practicals under computer science and engineering courses. Each mnemonic has its own hex codes. An assembler is a program which converts the code written in mnemonics into hexadecimal codes. The monitor program (part of microprocessor kit) translates the hex codes to corresponding actions to be performed by CPU.
