Suppose the hypothetical processor in Figure $1\mathrm{.}3$ has two $\frac{1}{O}$ instructions:

$30011=$ Load AC from $\frac{1}{O}$

$0110=$ Store $AC$ to $\frac{\text{I}}{O}$

$151111=$ Add to AC from memory

In these cases, the $12-$bit address identifies a particular external device. Show the program execution $($using the format of Figure $1\mathrm{.}4)$ for the following program:

i$.$ Load $AC$ from device $5.$

ii$.$ Add contents of memory address $940.$

iii. Store $AC$ to device $6.$

Assume that the next value retrieved from device $5$ is $8$ and that address $940$ contains value $3.$
