Include a 2-input NAND gate in the register of Fig. 6.1 and connect the gate output to the C inputs of all the flip-flops. One input of the NAND gate receives the clock pulses from the clock generator, and the other input of the NAND gate provides a parallel load control. Explain the operation of the modified register. Explain why this circuit might have operational problems.
