Write an ARM program to accept three decimal digits from a keyboard. Each digit is represented in the ASCII code (see Appendix E). Assume that these three dig- its represent a decimal integer in the range 0 to 999 and convert the integer into a binary number representation. The high-order digit is received first. To aid in this conversion, two tables of words are stored in the memory. Each table has 10 entries. The first table, starting at word location TENS, contains the binary representations for the decimal values 0, 10, 20,..., 90. The second table starts at word location HUNDREDS and contains the decimal values 0, 100, 200, ..., 900 in binary repre- sentation.
