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

Answer Posted / geo

address latch enable...in the case of microcontroller (8051)
& microprocessor 8085 the data line & low order 8 bit
address lines are multiplexed.in order to geting address
from this line we uses a latch.ALE is the line connected to
this latch saying that the take the address from the line.

NB: this is used only when we connecting our micro
controller to external mem.
