ALE (Address Latch Enable) is a control signal generated by the 8085 microprocessor during the first clock cycle (T1) of every machine cycle. It is an active-high output signal that indicates the lower 8-bit address (A0-A7) is present on the multiplexed Address/Data bus (AD0-AD7). In simple terms...
