$12\mathrm{.}1)$ You have a $6-$bit adder with an Accumulator and Clear $($CIrN$),$ as shown in the

figure below. Suppose the $x$ register contains a $6-$bit number from a previous

calculation, but we do not want this number. Instead, we want $x$ to equal the

value $3**Y.$

On the timing diagram below, draw values for inputs $Ad$ and $ClrN$ so that we will

have $x=3**Y$ held in the Accumulator.
