1. (20 pts.)
   1. (10 pts.) Use timerA_1 in UP mode to generate a 120 Hz square wave on the TA1.2 (P7.6) pin using Toggle output mode. Assume the system clock is at 48 MHz, and you are using SMCLK at 12 MHz for the timer clock. You will need to determine what value of prescale to use, and what value of TIMER_A1->CCR[0] and TIMER_A1->CCR[2] you need corresponding to that prescale value. Based on the values you calculate and the other specifications given above, write the code fragment needed to initialize timerA_1. Show your calculations.

prescale = _________

TIMER_A1->CCR[0] = ___________

TIMER_A1->CCR[2] = ___________

2. (10 pts.) Use timerA_2 in UP mode to generate a 60 Hz PWM signal on the TA2.3 (P6.6) pin. Assume the system clock is at 48 MHz, and you are using SMCLK at 12 MHz for the timer clock. Use a TOP value set by the TIMER_A2->CCR[0] register. Use reset/set mode on the output. Indicate what the minimum valid prescale value is. Based on that value, and the other specifications given above, write the code fragment needed to initialize timerA_2. Assume a duty cycle of 50 % initially to get the value for the TIMER_A2->CCR[3] register. Show your work.

prescale = ________________

TIMER_A2->CCR[3] = ________________
