circuits, with outputs, D–type flip–flops and control circuitry
providing multiplexed transmission of data directly from the input
bus or from the internal storage registers. Data on the A or B bus will
be loaded into the respective registers on the LOW–to–HIGH
transition of the appropriate clock pin (CAB or CBA). The four
fundamental data handling functions available are illustrated Figures
1 to 4.
