What is ALE? Explain the functions of ALE in 8085.

Answer Posted / ma forhad

ALE means Address Latch Enable.
ALE is a control signal of 8085 microprocessor.8085 has 16
bit address bus and lower (A0-A7) address are multiplexed
with data bus (D0-D7) which need to demultiplexed or
separate the data bus and address bus.
That means ALE use for separate the (AD0-AD7) bus to (A0-A7)
bus and (D0-D7) bus.
