Complete Instruction Set of 8085 Microprocessor

There are  total 256 instructions in  8085 microprocessor. These instructions are classified  into  seven categories  according  to their  functions these are :

a.Data copy  operations

b.Input output  operations

c.Arithmetic  operations

d.Logical  operations

e.Branch operations

f.Machine  control operations

g.Stack operations

To define  the format  of various  instructions followings variable names  and symbols  are used.

In order to understand  and write  assembly  language  program it is necessary to learn various  type of instructions and  also what  changes can be  made in registers and  flags by each  instruction after  execution.

Readers  who are  studying  microprocessor  for the  first  time are  advised to kip  the  instruction market  as they  might  be difficult to understand  at this  moment.

The above  mentioned  seven  categories  of instructions are discussed  in the followings  sections.
