Explanation:
Detailed explanation-1: -Address latch enable pin is used for reducing the pin in microprocessor. It is used for transferring data as well as also used for carrying address. When pin is low, it will allow address bus to transfer data and when it is in high state it will carry address.
Detailed explanation-2: -PIN 30 is called ALE (address latch enable). It is used to control the demultiplexing of address and data bus.
Detailed explanation-3: -ALE is used to demultiplexed/multiplexed data buses and address buses.
