没有板子，用PROTUES仿真，一涉及到中断等时就出错，各位看看，帮小弟一把，感激涕零！#include  <msp430x14x.h>
void main(void)
{
  WDTCTL = WDTPW + WDTHOLD;                 // Stop WDT
  P3DIR |= BIT4;                            // P3.4 output
  CCTL0 = CCIE;                             // CCR0 interrupt enabled
  CCR0 = 20000;
  TACTL = TASSEL_2 + MC_1;                  // SMCLK, upmode
   __bis_SR_register(CPUOFF+GIE);       //************** PROTUES仿真出错点（据我猜测）*******************//
  //__low_power_mode_0();
  //_BIS_SR(LPM0_bits + GIE);                 // Enter LPM0 w/ interrupt
}// Timer A0 interrupt service routine
#pragma vector=TIMERA0_VECTOR
__interrupt void Timer_A (void)
{
  P3OUT ^= BIT4;                            // Toggle P3.4
