Problem $1)$ Given the following instructions and their program addresses:

; in the main program:

$0$x$000$A call ProcA

$0$x$000$C inc r$3$

$...$

End$-$main: rjmp end$-$main

; in$-$ProcA

ProcA:

$0$x$0024$ rcall ProcB

$0$x$0025$ push r$18$

$...$

$0$x$003$A rcall ProcC

$...$

$0$x$003$E pop r$18$

$0$x$003$F ret

; in$-$ProcB

ProcB:

$0$x$0040$: push R$17$

$...$

pop R$17$

$0$x$004$C: Ret

; in ProcC

ProcC:

$0$x$0054$ push R$18$

$...$

$0$x$0061$ pop R$18$

$0$x$0062$ RET

Assuming that the value of R$18$ is $0$x$7$C$,$ R$17$ is $0$x$9$A and that the initial state of the stack is:

$$

$0$x$084$B $$ SP

$$

$$

$$

$0$x$085$F

Show the state of the stack, and the values of the PC and SP$,$ at each of the following points in

the dynamic execution of the program:

a$)$ immediately after executing the instruction at address $0$x$000$A$.$

b$)$ immediately after executing the instruction at address $0$x$0024.$

c$)$ immediately after executing the instruction at address $0$x$0040.$

d$)$ immediately after executing the instruction at address $0$x$004$C$.$

e$)$ immediately before executing the instruction at address $0$x$003$A$.$

f$)$ immediately after executing the instruction at address $0$x$003$A$.$

g$)$ immediately after executing the instruction at address $0$x$0054.$

h$)$ immediately before executing the instruction at address $0$x$0062.$

i$)$ immediately after executing the instruction at address $0$x$0062.$

j$)$ immediately before executing the instruction at address $0$x$003$F$.$

k$)$ immediately after executing the instruction at address $0$x$003$F$.$
