$8.(50$ pts$).$ Build an assembly language subroutine named IsEightTendie that will determine if the

value in R$8$ is evenly divisible by $8.$ If the value in R$8$ is evenly divisible by $8,$ your subroutine should

place the value $0$xFF on the stack, and if the value in R$8$ is not evenly divisible by $8,$ your subroutine

should place the value $0$x$00$ on the stack. Your subroutine must be placed at address $0$x$26$ in program

memory and must use only instructions that are contained in the CS$150$ AVR instruction subset. You

can use any registers that you want, but the value of all registers must be preserved for the caller. The

following code shows how your subroutine will be used:

$...$

call IsEightTendie ; check to see if R$8$ has what we$$re after

pop R$1$ ; put result into R$1$

$..($Note: Only these $30$ instructions should be used ADD, ADC, CP$,$ CPI, NEG, COM, AND, ANDI, EOR, OR$,$ ORI, LSR$,$ ASR, BRBC$,$ BRBS$,$ JMP$,$ RJMP$,$ CALL, RCALL, RET, RETI, MOV, IN$,$ OUT, LDI, LDS$,$ PUSH, POP, NOP, STS$)$
