Problem 2. Write the main program and subroutine that takes a set of 8-bit binary number, and converts them to their respective 2-character ASCII representation. Binary Hexadecimal ASCII Codes Examples: 1010 0101- A5 A' 41, 5'-35 1111000 i = F1 --> ‘F'= 46, 1-31 0000 00 10 = 02-> "O'= 30,'5'-32 0'-30, 5-32 41 35 46 31 30 32 A5 F1 02 sume that three parameters are passed to the subroutine. First, the starting address of the memory location where the se: of numbers are stored is passed in register X, second the starting address for the memory location where the ASCI codes will be stored is passed in register Y, and the length of the original data set is passed in register EB. a) Assume that threc parameters are passed to the subroutine. First, the s
