Description

This 4-bit register features parallel and serial inputs, parallel outputs, mode control, and two clock inputs. The register

has three mode operation:

• Parallel (broadside) load

• Shift right (the direction Q

• Shift left (the direction Q

Parallel loading is accomplished by applying the four bits of data and taking the mode control input high. The data is

loaded into the associated flip-flops and appears at the outputs after the high-to-low transition of the clock-2 input.

During loading, the entry of serial data is inhibited. Shift right is accomplished on the high-to-low transition of clock-1

when the mode control is low; shift left is accomplished on the high-to-low transition of clock-2 when the mode control

input may be applied commonly to clock-1 and clock-2 if both modes can be clocked from the same source. Changes at

the mode control input should normally be made while both clock inputs are low: however, conditions described in the

last three lines of the function table will also ensure that register contents are protected.
