Design a four-bit register implementation that uses T flip flops to store its values. This implementation differs from the one talked about in lecture, which used D flip flops. The register starts out with 0000 (all zeroes) as its first value.

Input Pins

Your input pins are the four input bits I3, I2, I1, and I0. You also have the input Clock. There is also an input named Enable. Hook this up to the enable pins on your flip flops.

Output Pins

Your output pins are the four output values D3, D2, D1, and D0.
