What is ale and explain the functions of ale in 8085, Computer Engineering

ALE-> Address latch enable...In the case of microcontroller (8051)& microprocessor 8085 the data line and low order 8 bit address lines are multiplexed. In order to getting address from this line we use a latch. ALE is the line linked to this latch saying that the take the address from the line.

NB: This is used only when we linking our microcontroller to external memory.
