4.4.2.2. What gives an independent resolution to the outputs of the high and low
byte?
One of the important practical examples is a system of 3 buses with a width of 8 bits each, as
shown in the figure below. The first bus is the input one, the second is the output bus, the third is bi-
directional.

Fig. 4-8: Example of a grouped connection of digital lines: three buses of 8 bits each.

The example shows an almost important case of implementing interfaces with various devices
that have an 8-bit bidirectional data bus, input and output control lines. It should be noted that DI14,
DI15, DI16 inputs have alternative synchronization functions (
