1. 소스 설명

full 소스는 아래 github를 통해 확인하세요.

#pragma vector = TIMER0_A0_VECTOR __interrupt void TimerA0_ISR (void) {     P1OUT ^= BIT0;                   // Toggle P1.0 } void main(void) {     P1DIR |= BIT0;                  // Set P1.0 to output direction     TA0CCTL0 = CCIE;                   // CCR0 interrupt enabled     TA0CTL = TASSEL_2 + MC_1 + ID_0; // SMCLK / 1 = 1 MHz / 1 = 1 MHz = 0.001 ms, upmode     TA0CCR0 =  1000; // 1ms     _BIS_SR(LPM0_bits + GIE);          // Enter LPM0 w/ interrupt }
