如图，
郁闷，为何会执行到这个地方，换了个片子也是。
用的672x

void main( void )
{
  // Stop watchdog timer to prevent time out reset
  WDTCTL = WDTPW + WDTHOLD;
  __disable_interrupt();
  ClkInit();
  P4SEL &= ~BIT1; P4DIR |= BIT1;   //蜂鸣器控制脚
  Timer2_A2_Init();
 __enable_interrupt();    
while(1)
{
    if( Button_Scan(1) == 1 )
    {
     P4OUT |= BIT1;
      _delay_ms(50);
    }
    else 
    {
       P4OUT &= ~BIT1;
    }
  
}
}
void main( void )
{
  // Stop watchdog timer to prevent time out reset
  WDTCTL = WDTPW + WDTHOLD;
  __disable_interrupt();
  ClkInit();
  P4SEL &= ~BIT1; P4DIR |= BIT1;   //蜂鸣器控制脚
  Timer2_A2_Init();
 __enable_interrupt();

{
    if( Button_Scan(1) == 1 )
    {
     P4OUT |= BIT1;
      _delay_ms(50);
    }
    else 
    {
       P4OUT &= ~BIT1;
    }
  
}
}

定时器代码
void Timer2_A2_Init(void)
{
TIMER2_A2->CCR0 = 409; //4096/10 = 100ms
TIMER2_A2->CTL |= 0x01c2; //ACLK、32768/8=4096中断开启
TIMER2_A2->CNT = 1; //定时器中的值，不能为0，
TIMER2_A2->CCTL0 |= CCIE;
TIMER2_A2->CTL |= 0x10; //Up mode
}
#pragma vector=TIMER2_A0_VECTOR
__interrupt void TIMER2_A2_ISR(void)
{
P4OUT |= BIT1;
}

代码停在什么地方

你好，谢谢你理睬我。之前的问题解决了，是我的过错。开了bit1 TAIE这个中断。我想问下您如下3个问题：

1： TAIE的中断入口地址是多少啊？

2：进入中断不必要清中断标志位吧？

3：

#pragma vector=TIMER2_A0_VECTOR
__interrupt void TIMER2_A0_ISR(void)

其中“TIMER2_A0_ISR”可以写成任意的名字吧？？？还有，为何要这样写？可以换个写法吗？

中断向量地址在msp430F67xx.h文件里有，Datasheet里也有向量列表

中断入口函数TIMER2_A0_ISR（），你只需要在函数里面写你的相应操作，不建议改函数名，每个芯片有不同Timer，每个Timer里面又有几个CCR，便于识别
