ONLY NEED HELP WITH PART 3. THANK YOU!

1. Create a 4-bit shift register that has the following capabilities 1. It can have its contents cleared 2. It can load the value on its input 3. It can shift its contents to the left 4. List all control inputs needed from the FSM 2. Create a 4-bit counter that has the following capabilities 1. It can have its value reset to zero 2. It can increment 3. It can decrement 4. List all control inputs needed by the FSM 3. Create a state machine that will do the following (in separate states) 1. Clear the register and reset the counter 2. Increment the counter twice 3. Decrement the counter once 4. Load the register with the value at its inputs 5. Shift the shift register twice Create the register, counter, and FSM as separate circuits.Create a 4th, top-level entity that will connect the FSM to the counter and register
