Given the following memory and register values for the IJVM machine discussed in class, execute the following microinstructions assuming that Main$1$ has already been executed.

Main$1$: PC $=$ PC $+1$; fetch; goto$($MBR$)$

$$

$1$: MAR $=$ SP $=$ SP $-1$; rd

$2$: H $=$ TOS

$3$: MDR $=$ TOS $=$ MDR $+$ H; wr; goto Main$1$

$$

After execution, fill in the boxes below with those registers $($in the register order given above$)$ that have changed and their final decimal value e$.$g$.$ MAR $=123.($Put a $0$ in any unused boxes.$)$

Then fill in the boxes below with those addresses $($in ascending order$)$ that have changed and their final decimal value separated by a space. Use the word address and not the byte address. e$.$g$.321=123.($Put a $0$ in unused boxes.$)$
