What is Addressing Modes in 8085 Microprocessor about?
The 8085 microprocessor uses address demultiplexing to allow the lower order address and data lines to be shared over a single bus. A latch is used to separate and hold the address values, which are only present for one clock cycle, from the data values. The latch is controlled by the Address Latch Enable (ALE) signal, holding the address when ALE is low and allowing data to pass when ALE is high. This address demultiplexing scheme allows the 8085 to reduce the number of pins needed while still supporting a
