code from the data bus via 74LS244 to the input of each latch, recanalization specified by the address decoder 7,415,138± latch latches. 74LS244 bus driver by the IOW and A9 control, when the output instruction is executed so that Lai) W and Ag at the same time is low, 74LS244 to play on, transmitting data on the data bus corresponding to each display latches (74LS273) on. In the circuit shown in the figure, from left to right each display bit address followed 100H, 101H, 10ZH, 103H, 104H, 105H.
