Write the process of address and data separation in De-multiplexed address/data bus in 8085 microprocessor. [5]
The 8085 microprocessor has only 40 pins. To reduce the pin count, Intel multiplexed the lower 8 bits of the address bus with the 8-bit data bus on the same set of pins, labeled AD0 - AD7. This means the same physical pins carry address information at one time and data information at another time...
