stm32定时器看不懂，求解释

/**
  * @brief  Sets the TIMx Capture Compare1 Register value
  * @param  TIMx: where x can be 1 to 17 except 6 and 7 to select the TIM peripheral.
  * @param  Compare1: specifies the Capture Compare1 register new value.
  * @retval None
  */这每一行是什么意思?英语差看不懂。求翻译。以及下面的麻烦也解释一下
void TIM_SetCompare1(TIM_TypeDef* TIMx, uint16_t Compare1)
{
  /* Check the parameters */
  assert_param(IS_TIM_LIST8_PERIPH(TIMx));
  /* Set the Capture Compare1 Register value */
  TIMx->CCR1 = Compare1;
}
/**
  * @brief  Sets the TIMx Capture Compare2 Register value
  * @param  TIMx: where x can be 1, 2, 3, 4, 5, 8, 9, 12 or 15 to select the TIM peripheral.
  * @param  Compare2: specifies the Capture Compare2 register new value.
  * @retval None
  */
void TIM_SetCompare2(TIM_TypeDef* TIMx, uint16_t Compare2)
{
  /* Check the parameters */
  assert_param(IS_TIM_LIST6_PERIPH(TIMx));
  /* Set the Capture Compare2 Register value */
  TIMx->CCR2 = Compare2;
}

这个是设置定时器比较的吧，首先检查定时器参数是否正确，然后把要比较的数值compare1保持到捕获/比较寄存器1（CCR1）中。至于怎样工作的。可以看一下STM32数据手册。
