6. Write a program that takes character data 'a' through 'z' and returns the character in upper case value for the same letter. Note that the ASCII table is in Appendix C of your Hohl text (or available via a Google images search). You should put a valid value 'a' through 'z' in r5 at the start of your program and the resulting value 'A' through 'Z' should be placed in r6 at the conclusion of your code. Again, show your code works with the Keil tools by grabbing a screen shot with your name somewhere on the screen.
