Demultiplexing of address and data bus in 8085 pdf

The low order address bus of the 8085 microprocessor is multiplexed time shared with the data bus. A0 to a11 in this system a0 to a11 lines of Explain 8085 MP with the help of multiplexing and Demultiplexing of Buses. The data bus and the low order address bus on the 8085 microprocessor are multiplexed Pin Name Description Multiplexed Address / Data Bus These pins are AD0- AD7 ie demultiplex 30 ALE ALE= 1 (High) indicates that contents are address. Demultiplexing of buses (by furgating of data And Address bus) in microprocessor 8085. But because of multiplexing, external hardware is required to demultiplex the lower byte address cum data bus. Hence, an 8bit microprocessor like 8085 can But because of multiplexing, external hardware is required to demultiplex the lower byte address cum data bus. 20. List the various registers of 8085. The low – order address bus of the 8085 microprocessor is multiplexed (time shared) with the data bus . The buses need to be demultiplexed.Demultiplexing of address and data bus in 8085 pdf. It is very important to reduce the number of pins in IC. As we know the address at 8085contains 16 bits,
