$(2)$ Based on the provided microcode $($control signals$),$ write a description of the operation in either RTL instruction format or plain English. Simplify the description if possible. For example, if the datapath performs R$2=$ R$1$ OR $0,$ it would be better to write R$2=$ R$1$ or $"$R$2$ gets the value of R$1".$ Note that everything not bolded is the same in all rows.
