问 现象：不能进入timer1中断服务程序
      观察TOV1 OCF1B OCF1A 已经置位, TOIE1 OCIE1B OCIE1A 也已经0置位
      SREG.7 置位

      timer0正常.......
      为何？？？？？？？急~~~~~~~~~~~~~~~~~~~~``

iccAVR 6.22b + AVR studio 4.05

void timer1_init(void)
{
TCCR1B = 0x00; //stop
TCNT1H = 0x85; //setup
TCNT1L = 0xEE;
OCR1AH = 0x7A;
OCR1AL = 0x12;
OCR1BH = 0x7A;
OCR1BL = 0x12;
TCCR1A = 0x00;
TCCR1B = 0x01; //start Timer
}
main()
{
MCUCR = 0x00;
EIFR  = 0x00; //external interrupts sources
EIMSK = 0x00;
//TIMSK = 0x03; //ONLY enable the timer0 for test the timer....
TIMSK = 0X1C;//Enable the timer1.........
//TIMSK = 0xDF; //timer interrupt sources
ETIMSK = 0x00;//about timer3
SEI(); //re-enable interrupts

... ...

}






答 1: 盼复 答 2: 已经解决，纯软件仿真的问题，使用JTAG没问题
