Clear GIE problem

try _bic_SR_register_on_exit(GIE);

Hi Hcmut!

hcmut said:

want to disable gobal interrupt in timer ISR by ONLY GIE, but no effect

What does that mean in deatil? Is the bit still set in the register overview when single stepping through the code? Add another expression after the __bic_sr instruction and single step over the instruction. Did you check if the rest of your program works properly?

Dennis

yes, I tried, but the code in While not run, how I can fix that?

#include <msp430.h> 
#include "MSP430_MACROs.h"
/*
 * main.c
 */
void TIM_TRIG_ADCs_CFG(){
    TA0CCTL0 &= ~CCIE;
    TACTL = TASSEL_2 + MC_1; // Set the timer A to SMCLCK, Continuous
    TA0CCR0 = 50000-1;
    TA0CCTL0 |= CCIE;
    _BIS_SR(GIE);
//  __enable_interrupt();
}
void delay_ms (int t)
{
    int i;
    for (i = 0; i<t; i++ )
        _delay_cycles(16000);
}
int timerCount=0,tc1=0, ena =0;
int count=0;
int main(void) {
    WDTCTL = WDTPW | WDTHOLD;   // Stop watchdog timer

    if (CALBC1_16MHZ==0xFF)                 // If calibration constant erased
    {
        while(1);                           // do not load, trap CPU!!
    }
    // configure clock to 16 MHz
    BCSCTL1 = CALBC1_16MHZ;                 // DCO = 16 MHz
    DCOCTL = CALDCO_16MHZ;
    P1DIR |= LED_ALL;
    P1OUT &= ~LED_ALL;
    TIM_TRIG_ADCs_CFG();
    while(1){
    	if(ena){
    		T(1,6);
    		delay_ms(100);
    	}
    return 0;
}
}

#pragma vector=TIMER0_A0_VECTOR
__interrupt void Timer_A00 (void)
{

    if((!((++timerCount)%96))){
        T(1,0);
        if(++tc1==8){
        	ena =1 ;
            __bic_SR_register_on_exit(GIE);
        }
    }
}

Let's back up a bit. Can you explain what you are trying to do?

I want to make a Timer ISR, after occured,, handle something, I want to stop timer, and go back to main loop, I dont want to use LPM,

>handle something, I want to stop timer, and go back to main loop, I dont want to use LPM,

Why not LPM0?, it stops main.c in its track waiting for a ISR to tell it to keep going.
Does that not sound what you want?

If you want cooperative-multitasking,
make a event machine in main that only go to lpm0 if all events are 0, use union to check all 16bits in one word.
and make 3 event share a free-running (continuous) timer by grabbing T0AR on the fly as a starting point for itself.

//╞════════════════════════════ TA0 ISR ══════════════════════════════════════╡  
#pragma vector=TIMER0_A0_VECTOR			// Timer A0_0 interrupt service routine
__interrupt void Timer_A0 (void)                 // TA0CCR0 CCIFG
{  	   		
        event.alert = 1;                         // optional flag set for: ALERT
        TA0CCTL0 = 0;                            // one time shoot, turn off irq
        __bic_SR_register_on_exit(LPM0_bits);
}
