Instruction Set and their types, Functions with examples and Addressing Models of 8085 Microprocessor

Instruction Set of 8085 Microprocessor An instruction is a command given to the computer to perform a specified operation on the given data. In 8085 microprocessor, the instructions are classified into five (5) groups. They are, Data Transfer Group  Arithmetic Group Logical Group Branch Control Group I/O and Machine Control Group Addressing Models: Each instruction requires certain data on which it has to operate. In Intel 8085 Microprocessor, there are 4 types of addressing mode. More on Addressing Models>>> Data Transfer Group MOV r1, r2 This means the data of register - 2 will move to register - 1                                         Example - MOV A, B MOV r, M This means the data stored in ((H - L)) will move to the specified register.                                         Example - MOV B, M MOV M, r This means the data in the specified register will move to ((H-L)).                                         Example - MOV M, B MVI r, data This means the given data will
