[STM32定时器学习-004]一个小小的错误

STM32Cube_FW_F0_V1.6.0中这几行代码有错,UDIS置位才是禁止更新事件,官方写错了.给官方提交了.

/**
  * @brief  Enable update event generation.
  * @rmtoll CR1          UDIS          LL_TIM_EnableUpdateEvent
  * @param  TIMx Timer instance
  * @retval None
  */
__STATIC_INLINE void LL_TIM_EnableUpdateEvent(TIM_TypeDef *TIMx)
{
  SET_BIT(TIMx->CR1, TIM_CR1_UDIS);
}
/**
  * @brief  Disable update event generation.
  * @rmtoll CR1          UDIS          LL_TIM_DisableUpdateEvent
  * @param  TIMx Timer instance
  * @retval None
  */
__STATIC_INLINE void LL_TIM_DisableUpdateEvent(TIM_TypeDef *TIMx)
{
  CLEAR_BIT(TIMx->CR1, TIM_CR1_UDIS);
}
/**
  * @brief  Indicates whether update event generation is enabled.
  * @rmtoll CR1          UDIS          LL_TIM_IsEnabledUpdateEvent
  * @param  TIMx Timer instance
  * @retval State of bit (1 or 0).
  */
__STATIC_INLINE uint32_t LL_TIM_IsEnabledUpdateEvent(TIM_TypeDef *TIMx)
{
  return (READ_BIT(TIMx->CR1, TIM_CR1_UDIS) == (TIM_CR1_UDIS));
}

大家应该看出写反了.
