Timer A UP mode 中断

Timer_A, Toggle P1.0, CCR0 Up Mode ISR, DCO SMCLK

// Description: Toggle P1.0 using software and TA_0 ISR. Timer_A is
// configured for up mode, thus the timer overflows when TAR counts to CCR0.

1 void Timer0_Init(void)
2 {
3 
4       CCTL0 = CCIE;                             // CCR0 interrupt enabled
5       CCR0 = 5000;                              //frequency SMCLK/5000*2;
6       TACTL = TASSEL_2 + MC_1;                  // SMCLK, upmode
7 }

void Timer0_Init(void)

中断函数

1 #pragma vector=TIMER0_A0_VECTOR
2 
3 __interrupt void TimerA0(void)
4 
5 {
6 
7     P1OUT ^= RED_LED;
8 
9 }

__interrupt void TimerA0(void)

屏蔽中断：
CCTL0 ^= CCIE; //在开启定时器中断与关闭间转换。

因为同时使用的PWM与此定时器冲突所以又使用了定时器A1

 1 void Timer1_Init()
 2 
 3 {
 4 
 5 TA1CCTL0 = CCIE;
 6 
 7 TA1CCR0 = 5000;    
 8 
 9 TA1CTL |= TASSEL_2+MC_1+TACLR;  
10 
11 }

void Timer1_Init()

中断

1 #pragma vector=TIMER1_A0_VECTOR
2 
3 __interrupt void TimerA1(void)
4 
5 {
6 
7     P1OUT ^= RED_LED;
8 
9 }

__interrupt void TimerA1(void)

注意寄存器名字与中断向量的名字
