# include
void main(void)
{
WDTCTL = WDT_MDLY_32; //  定时周期为32ms
SFRIE1 |= WDTIE; //  使能WDT 中断
P1DIR |= 0x01; // P1.0 输出
__enable_interrupt(); //  系统中断允许
for (;;)
{
//  进入 LPM0
__bis_SR_register(LPM0_bits);
__no_operation();
}
}
#pragma vector= WDT_VECTOR
__interrupt void watchdog_timer (void)
{
P1OUT ^= 0x01; // P1.0 取反
}
