我用STM8S103F3做双路输入捕获，TIM1配置好并可以正常工作，但配置TIM2的时候发现一个问题，TIM2没有TIM2_SMCR。于是问题就出现了，配了很久出处还是不正常，请问高手怎么配置TIM2?
TIM1的配置如下：
  CLK_PCKENR1 |= 0x80;

  TIM1_PSCRH = 0;
  TIM1_PSCRL = TIM1_DIV;
  TIM1_CCMR1 |= 0x31;          //fSAMPLING=fMASTER, N = 8;
                              //No prescaler, capture is made each time an edge is detected on the capture input;
                              //CC1 channel is configured as input, IC1 is mapped on TI1FP1;
  TIM1_CCER1 &= ~0x02;       //上升沿触发
  TIM1_SMCR |= 0X54;          //TI1FP1触发；复位模式
  TIM1_CCER1 |= 0x01;          //使能输入捕获1
  TIM1_CR1 = 0x01;             //Enabled update request source;Counter enabled;
