What is the use of $AD_7-AD_0$ in 8085 microprocessor? Explain address de-multiplexing process in 8085 microprocessor with suitable diagram. [5]
--- The 8085 microprocessor has only 40 pins. To reduce the pin count while still supporting a 16-bit address bus and an 8-bit data bus, Intel used a technique called multiplexing. The pins AD₇-AD₀ serve a dual purpose: Time Period Function ------ First half of machine cycle (T1) Carry the lower ...
