@brief: 结构体说明
@note 参数说明
@ref: 结构体成员取值选项

结构体成员取值的注释格式

以该结构体成员其后的注释为例, 可取值 @ref DMA_data_transfer_direction

1 2	uint32_t DMA_DIR; /!< Specifies if the peripheral is the source or destination. This parameter can be a value of @ref DMA_data_transfer_direction /

则下文中需出现注释

/** @defgroup DMA_data_transfer_direction 
  * @{
  */

#define DMA_DIR_PeripheralDST              ((uint32_t)0x00000010)
#define DMA_DIR_PeripheralSRC              ((uint32_t)0x00000000)
#define IS_DMA_DIR(DIR) (((DIR) == DMA_DIR_PeripheralDST) || \
                         ((DIR) == DMA_DIR_PeripheralSRC))
/**
  * @}
  */

通常包含以下部分

@defgroup : 为可取值组的名字需与@ref后的名字对应
@{ @}: 取值组前后需要用@大括号括起来, 中间为结构体成员可以取的变量
@ref : 写在结构体成员之后, 需要与后文@defgroup的名字对应
