430f149 interrupt can't enter? [Copy link]

I made a board before, and the same program can work normally on other boards, but this one can't enter the interrupt, I don't know why. void main(void) { WDTCTL = WDTPW + WDTHOLD; //Turn off watchdog// P6DIR |= BIT2;P6OUT |= BIT2; //Turn off level conversion CCTL0 = CCIE; //Enable CCR0 interrupt CCR0 = 16384; //Set period 0.5S TACTL = TASSEL_1 + ID_0 + MC_1; //Select ACLK as the clock source of timer A, up counting mode P4DIR = 0x3E; //Set P1.3, P1.4 port direction to output P4OUT = 0x00; _EINT(); //Enable global interrupt LPM3; //CPU enters LPM3 mode//while(1) // { // } }#pragma vector = TIMERA0_VECTOR __interrupt void Timer_A (void) { }

Keep while infinite loop

Even after keeping it, I can't get in,,,

Turn off and enter low power consumption level 3

Follow the debug to see where the program stops. ——No response, but the moment of stopping debug is displayed in ISR_TRAP.ASM, then check whether the interrupt vector ID is correct and add the interrupt response function. The key configuration is the following three sentences, confirm them, and you can confirm whether it is OK. CCTL0 = CCIE; //Enable CCR0 interrupt CCR0 = 16384; //Set the period to 0.5S TACTL = TASSEL_1 + ID_0 + MC_1; //Select ACLK as the clock source of timer A, count up mode
