#include "io430.h"
#include "io430g2332.h"

void main(void)
{
unsigned long Delay=0;
Clock_Config();
IO_Config();
IO_State_Init();
TIMER_Config();
while(1)
{}

}

#pragma vector = TIMER0_A1_VECTOR
__interrupt void Timer_A (void)
{}

void Clock_Config(void)
{
WDTCTL = WDTPW + WDTHOLD; //关闭看门狗
DCOCTL = DCO1+DCO0;
BCSCTL1 = XT2OFF+RSEL3;
BCSCTL2 = 0;
}

void TIMER_Config(void)
{
TACTL |= TASSEL_2+ID_0+MC_1+TAIE; //时钟选择SMCLK,不分频，增计数模式,使能中断
//CCTL0 = CCIE; //使能CCR0中断
//CCR0 = 2047; //设定周期0.5S
CCR0 = TIME;
TAR = TIME;

CCTL0 = CCIE; // CCR0 interrupt enabled
CCR0 = 500;
}

程序设置基本就是这样，#pragma vector = TIMER0_A1_VECTOR或者TIMER0_A0_VECTOR都不能进入中断，没用过msp430，不知道如何配置；还有那个全局中断IE1里面，好像没有和定时器有关的位吧？希望能得到尽快解决，最好有MSP430G2332的初始化配置程序可以学习下。本人QQ12697909。希望有技术支持帮忙解决。

请参考下面能进Timer0 A1中断的例子：

//******************************************************************************
//  MSP430G2xx2 Demo - Timer_A, Toggle P1.0, CCR1 Cont. Mode ISR, DCO SMCLK
//
//  Description: Toggle P1.0 using software and TA_1 ISR. Toggles every
//  50000 SMCLK cycles. SMCLK provides clock source for TACLK.
//  During the TA_1 ISR, P1.0 is toggled and 50000 clock cycles are added to
//  CCR0. TA_1 ISR is triggered every 50000 cycles. CPU is normally off and
//  used only during TA_ISR. Proper use of the TA0IV interrupt vector generator
//  is demonstrated.
//  ACLK = n/a, MCLK = SMCLK = TACLK = default DCO
//

int main(void)
{
  WDTCTL = WDTPW + WDTHOLD;                 // Stop WDT
  P1DIR |= 0x01;                            // P1.0 output
  CCTL1 = CCIE;                             // CCR1 interrupt enabled
  CCR1 = 50000;
  TACTL = TASSEL_2 + MC_2;                  // SMCLK, Contmode

  _BIS_SR(LPM0_bits + GIE);                 // Enter LPM0 w/ interrupt
}

// Timer_A3 Interrupt Vector (TA0IV) handler
#pragma vector=TIMER0_A1_VECTOR
__interrupt void Timer_A(void)
{
  switch( TA0IV )
  {
  case  2:                                  // CCR1
    {
    P1OUT ^= 0x01;                          // Toggle P1.0
    CCR1 += 50000;                          // Add Offset to CCR1
    }
           break;
  case  4: break;                           // CCR2 not used
  case 10: break;                           // overflow not used
 }
}
