A universal shift register can shift in both the left-to-right and right-to-left directions, and it has parallel-load capability. Draw a circuit for such a shift register.

Explanation:

A unidirectional shift register allows for the capability of shifting in one direction as the name unidirectional implies.

A bidirectional shift register has the capabilities of shifting in both the left to right and right to left directions.

For a Universal shift register, there are possibilities of bidirectional shifts and parallel-load capabilities that have the following properties.

There is the existence of a clear control input whose main  FUNCTION is to set all the register to 0.'

A shift control to both the right and left direction to enable both the shift right operation and shift left operation.

Finally, a parallel-load control whose function is to activate a parallel transfer from input to output.

The diagram for the circuit for such a shift register can be seen in the diagram attached below.

the warning light flashes for a second or two when the engine starts. if it stays on, there's must be something wrong with the coolant. you should never dare to continue driving when the light is on. pull over as soon as possible and shut the engine off.

hope this is what you're talking about
