Address Bus
The address bus is the group of 16 lines. It is used to carry the address of memory location and addresses of input and output ports as shown. It is a unidirectional bus. It means the bits can flow only in one direction i e microprocessor to the peripherals. The address line are identified by A15-A0 .
