关于TimerA输出方波后delay 650ms再持续输出方波

各位好, 想在以下程式输出波形7次后 (350ms) , 加入延迟副程式 (650ms) 后再输出波形* 7持续循环, 主要是想控制LED闪烁的频率, 但因为找不到可参考的延迟副程式进行学习, 想请教各位是否有程式范例可提供小弟进行研究? 谢谢

  WDTCTL = WDTPW + WDTHOLD;
  
  // Timer, ADC => EMG
  P8DIR |= 0x01;
  P8OUT &= ~0x01;
  TA1CCR0 = 2500;
  TA1CCR2 = 2250;
  TA1CCTL0 |= OUTMOD_7 + CCIE;
  TA1CCTL2 |= OUTMOD_7 + CCIE;
  TA1CTL |= TASSEL_2 + MC_3 + TACLR;
  
  while(1)
    __bis_SR_register(LPM0_bits + GIE);
}
