Programs of microprocessor
Microprocessor cannot understand a program written in Assembly Language . Instruction are divided into bit pattern of word in byte as op-code(operation code) and operation Instruction format has three types 1.One byte-has op-code 2.Two byte- has op-code and address 3.Three byte -has code and address lower byte and address higher byte opcode 1 byte opcode Data / address 2 byte opcode Data / address Lower byte Data Address Higher byte 3 byte Instructions set for 8085 are classified into five categories: 1.Data transfer group instructions 2.Arithmetic group of instrructions 3.Logical group 4.Branching group 5.Machine Level A program known in Assembler is used to covert a Assembly language program to machine language. I) Data transfer copy operation:- 1)Load a 8 bit number in a register 2)Copy from Register to Register 3)Copy between Register and Memory 4)Copy between Input/Output Port and Accumulator 5)Load a 16 bit number in a Register pair 6) Cop...
