Which of the following is NOT a fundamental operational state or action of a digital flip-flop?

A flip-flop is a 1-bit bistable multivibrator storage cell with two stable output states ($Q=1$ and $Q=0$). The four fundamental operations that can be performed on flip-flops (such as JK, SR, D, and T flip-flops) are:

1. Set: Forcing the output to logic 1 ($Q=1$).

2. Reset / Clear: Forcing the output to logic 0 ($Q=0$).

3. Hold / No Change: Retaining the previous state ($Q_{next} = Q_{prev}$).

4. Toggle: Inverting the output to its complement ($Q_{next} = \overline{Q_{prev}}$).

Arithmetic multiplication is a complex combinational/sequential arithmetic process, not a primitive operational state of a single flip-flop.
