Trouble getting TIMERA ISR to trigger on MSP430FR5739

Hi,

I am new to the MSP430 from ARM based controllers, and I'm using the MSP-FET430U40A board with the MSP430FR5xxx 40-Pin FET tool with an MSP430FR5739.  I have a very simple program that sets up TimerA0 and TimerA1.  Timer A0 outputs a PWM signal on P1.1, and I want to set Timer A1 to trigger an interrupt at some configurable time interval so that I can modify the duty cycle of the PWM signal generated by Timer A0.  I cannot for the life of me get any timer interrupt to call.  I've read every post and tried all of the suggestions with no success, so I was hoping that someone here could get me on the right track.  I'm using Code Composer Studio 6.0.1 to develop the project.  This is the code that I have so far:

My Main Function:

#include <msp430.h>				
#include "Setup.h"
#include "MPPT.h"
#include "ADCRead.h"


int main(void) {
	WDTCTL = WDTPW | WDTHOLD;		// Stop watchdog timer
	int i = 0;
	Sys_Init();
	while (1);
}

My Setup function:

void Sys_Init(){
	  CSCTL0_H = 0xA5;
	  CSCTL1 = DCOFSEL0 + DCOFSEL1;								// Set DCO max setting = 8MHz
	  CSCTL2 = SELA__DCOCLK + SELM__DCOCLK + SELS__DCOCLK;		// set all clocks to be sourced from DCO
	  CSCTL3 = DIVA__2 + DIVM__2 + DIVS__32;					// set all dividers
	  	  	  	  	  	  	  	  	  	  	  					//ACLK is divided by 2 (4MHz), Mclock divided by 2 (4MHz)
	  	  	  	  	  	  	  	  	  	  	  	  	  	  	  	//SMCLK is divided by 32 (250 kHz)
//	  CSCTL4 = SMCLKOFF;										//Turn SMCLK off to save power

	  P1DIR |= BIT0;				                       		// P1.0 output
	  P1SEL0 |= BIT0;               				       		// P1.0 options select
	  TA0CCR0 = CYCLES_30KHZ;									// PWM Period (to get 30 kHz, -> 4MHz/30kHz = 133)
	  TA0CCTL1 = OUTMOD_7 + CCIE;                      				// CCR1 reset/set mode
	  TA0CCR1 = 66;                            					// CCR1 PWM duty cycle		(50% of value in TA0CCR0 is half of duty cycle)
	  TA0CTL = TASSEL__ACLK + MC__UP + TACLR;					// ACLK as source, up mode, clear Timer A0

	  TA1CCTL0 = CCIE;// + OUTMOD_7;
	  TA1CCR0 = CYCLES_2SEC/8;									//Timer A1 resets every 2 seconds
	  TA1CTL = TASSEL__SMCLK + MC__UP + TACLR + ID_2;			// SMCLK as source, up mode, clea	r Timer A1, Input Clock/8 (31.25 KHz)
//			  + TAIE;											//Timer A1 interrupt enabled
}

My ISRs for the Timers (I've enabled the CCR0 interrupt for both timers just to see if I can get anything to trigger, which I can't):

#pragma vector=TIMER1_A0_VECTOR
__interrupt void TIMER1_A0(void){
	LPM0_EXIT;
	TA1CTL &= ~TAIFG;			//Clear the interrupt flag
	int temp = TA1IV;
//	TA1IV = 0;					//clear interrupt vector
}

#pragma vector=TIMER0_A0_VECTOR
__interrupt void TIMER0_A0(void){
	LPM0_EXIT;
	TA0CTL &= ~TAIFG;			//Clear the interrupt flag
	int temp = TA0IV;
//	TA1IV = 0;					//clear interrupt vector
}
#pragma vector=TIMER1_A1_VECTOR
__interrupt void TIMER1_A1(void){
	LPM0_EXIT;
	TA1CTL &= ~TAIFG;			//Clear the interrupt flag
	int temp = TA1IV;
//	TA1IV = 0;					//clear interrupt vector
}
#pragma vector=TIMER0_A1_VECTOR
__interrupt void TIMER0_A1(void){
	LPM0_EXIT;
	TA0CTL &= ~TAIFG;			//Clear the interrupt flag
	int temp = TA0IV;
//	TA1IV = 0;					//clear interrupt vector
}

As always, thank you in advance for any help you can provide.
