我用flag作为标志，发现并没有进入中断，为什么啊？哪里错了？

2231我试过了，程序没问题啊
#include “msp430g2231.h”
void main(void)
{
WDTCTL = WDTPW + WDTHOLD; // Stop WDT
P1SEL &= ~BIT5;
P1DIR |= BIT5; // P1.5 output
TACTL = TASSEL1 + TACLR; // SMCLK, contmode
TACCTL0 = CCIE; // CCR0 interrupt enabled
TACCR0 = 1748;
TACTL |= MC0;
_EINT();
while (1)
{
LPM0;
} // Enter LPM0 w/ interrupt
}
// Timer A0 interrupt service routine
#pragma vector=TIMERA0_VECTOR
__interrupt void Timer_A (void)
{
P1OUT ^= BIT5; // Toggle P1.0
}
可以进中断</msp430g2231.h>
