$10.(50$ pts$).$ Build an assembly language subroutine named ExportR$1$Bits that copy bits from R$1$

into other registers. Your subroutine will copy bits $7,5,$ and $0$ of R$1$ into R$31,$ and will copy bits $6,3,$

and $1$ of R$1$ into R$30,$ and will copy bits $4$ and $2$ of R$1$ into R$29.$ The bits found in R$1$ must occupy the

same places in the destination register as they did in R$1.$ A diagram of where each bit in R$1$ must go is

shown below:

R$1[$ R$31$ R$30$ R$31$ R$29$ R$30$ R$29$ R$30$ R$31]$

For example, suppose that R$1$ contains the value $11111111$ and that R$29,$ R$30,$ and R$31$ all contain $0$

when your function is called. When your function finishes, R$31$ will contain $10100001,$ R$30$ will

contain $01001010,$ and R$29$ will contain $00010100.$ As another example, suppose that R$1$ contains the

value $10011101$ and that R$29,$ R$30,$ and R$31$ all contain $0$ when your function is called. When your

function finishes R$31$ will contain the value $10000001,$ R$30$ will contain the value $00001000,$ and R$29$

will contain the value $00010100.$ Your subroutine must use only instructions that are contained in the

CS$150$ AVR instruction subset. The next page is blank if you need more space to work. $($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$)$
