Bus Organisation

Set of  communication lines in microprocessor  which  carry  bits from microprocessor to  peripherals  ( memory  inputs ports  output  ports  and other chips  or devices  connected to microprocessor) and also  from peripherals  to microprocessor  called  busses. There are three  sets of busses in 8085 microprocessor.

a.Address bus

b.Data bus

c.Control bus
