Build an assembly language subroutine named SuperfyRO that will find the largest of the values in the registers RO, R1, R2, and R3 and copy that value into RO. For example, if RO contains 28, R1 contains 15, R2 contains 3, and R4 contains 77 when your subroutine is called, when your subroutine is finished RO will contain 77, R1 will contain 15, R2 will contain 3, and R4 will contain 77. Your subroutine must be placed at address Ox30 in program memory and must use only instructions that are contained in the CS150 AVR instruction subset. Your subroutine cannot use any data memory locations or any registers other than RO, R1, R2, and R3 to solve this problem.
