The figure below demonstrates how this is done: Address latch enable, used to demultiplex the address/data bus on port 0. Figure 1.2 ale in use psen pin. We get the lower half of the address from port 0 and the upper half from port 2. An active high signal at this pin represents the presence of address in the multiplexed address and data bus. Pins 32 to 39 −. This is done using ale pulses, which help to latch the address to the external bus. Pin 31 − this is ale pin which stands for address latch enable.
