Build a CS$150$ AVR assembly language subroutine called NumOnesInR$0$ that will

count the number of $1$ bits in R$0$ and place the result in R$5.$ For example if R$0$

contains the value $01010110$ when your subroutine is called, your subroutine will

write the value $4$ into R$5.$ When your subroutine is finished, the value of R$0$ must

be the same as it was before your subroutine was called. You should direct the

assembler to place your subroutine at address $0$x$30$ in program memory. Your

subroutine must use only instructions that appear in the CS$150$ AVR

instruction subset. $($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$)$
