What does a constant on a shift register do?

[Peanut 1292]

Does a constant on a shift register do anything? How does the constant effect the outcome?

[Harold_Timmis]

Well it initializes the shift register.

[altenbach]

What is your definition of "on a shift register"? Can you show an image or attach a VI?

A shift register can be initialized with a constant to give it a starting value. The shift regsiter value can later change from within the code by wiring a new value to the right register.

If the initialization and the right shift register are both wired to the same constant, the shift register is not needed because the value never changes.
