For the MSP430, write a program that uses a timer interrupt to create a 400Hz, 30% duty cycle signal on P9.7. Do not disable the watchdog timer. and Use an ADC interrupt to turn on the red LED whenever the analog voltage on P9.3 is above 2V. Turn off the red LED if P9.3 is at or below 2V. and Send the message 0x44 on the UART TXD pin at 9600 baud once every 800ms. and Use a timer interrupt to create a 300Hz, 50% duty cycle signal on P1.7 whenever the P1.2 button is pushed and held. If the P1.2 button is not pushed (that is, released), P1.7 should be LO. The solution should contain functions, ISRs as appropriate. The solution should contain comments for each and every line of code. (This will help me to debug your code in case the solution has errors.)
