Write an assembly program that will update an input string. Each uppercase letter in the input string should be replaced by the corresponding lowercase letter. Assume that a string does not include more than one line. Count the number of changes and display the output at port P3. Assume the input string is "Welcome to MSP430 Assembly!" then the correct results for testing purpose are shown below: 2. [65 pts] Updated string: "welcome to msp430 assembly!" Total Number of Changes: 5 Note: You can also download this program to the MSP430FG4618 Experimenter's Board and run
