求解，在使用time3 PWM输出时，编译器debug时一直提示idata溢出
寄存器设置时，赋值有错误吗？
寄存器配置应该不会有问题，代码如下：
/* Setup TIMER3 PWM at alternate location 2 */ PERCFG |= 0x20; // TIME3 at location 2 P1SEL |= 0x40; // Peripheral function on TIMER3 (P1_6 P1_7) P2SEL |= 0x20; // Give priority to TIMER3 over USART 1 for P1_6 P1_7 pins.
//set the time ticks to 32M , CLKCONCMD[5:3] CLKCONCMD &= ~0x08; CLKCONCMD &= ~0x10; CLKCONCMD &= ~0x20; //set the Prescaler divider to 128 T3CTL |= 0x80; T3CTL |= 0x40; T3CTL |= 0x20; //set the timer3 mode T3CTL |= 0x03; //up/down //set the time3 channel0 mode T3CCTL0 |= 0x04; //compare mode T3CCTL0 |= 0x20; //clear output on compare_up,set on 0 T3CCTL0 &= ~0x10; T3CCTL0 &= ~0x08; //clear counter T3CTL |= 0x04; //set the compare value T3CC0 = 0x40; //set the interruptT3CTL |= 0x08; //overflow interrupt maskT3CCTL0 |= 0x40; //channel 0 interrupt mask IEN0 |= 0x80; //enable interrupt IEN1 |= 0x08; //timer3 interrupt enable // //start the pwm T3CTL |= 0x10;
还有如果我在上面的代码后面加while（1）pwm波形输出正常，但是去掉while（1）后，系统跑起来后看波形根本没按设定的速率输出，一点规律没有
