Write a MC68H12 assembly language program to find the largest number in an array of ten 8-bit numbers. The array is stored in memory locations starting at address $1100. Use branch instructions and loops.
Write and test your programs using Freescale CodeWarrior (you may use another assembler if you so wish). You should also turn in a printed report that contains the following:
1. Your programs, accompanied by proper documentation (comments)
2. Initial, intermediate and final snapshots of the CodeWarrior status window (the window that shows the values of registers) and the CodeWarrior memory window, for each part of this homework, A, B, and C.
