弱弱的问一下，core_cm3.h中的结构体变量问题

daiqh

core_cm3.h当中有如下一段结构体：
 typedef struct
{
  __IO uint32_t ISER[8];                      /*!< Offset: 0x000  Interrupt Set Enable Register           */
       uint32_t RESERVED0[24];                                  
  __IO uint32_t ICER[8];                      /*!< Offset: 0x080  Interrupt Clear Enable Register         */
       uint32_t RSERVED1[24];                                   
  __IO uint32_t ISPR[8];                      /*!< Offset: 0x100  Interrupt Set Pending Register          */
       uint32_t RESERVED2[24];                                  
  __IO uint32_t ICPR[8];                      /*!< Offset: 0x180  Interrupt Clear Pending Register        */
       uint32_t RESERVED3[24];                                  
  __IO uint32_t IABR[8];                      /*!< Offset: 0x200  Interrupt Active bit Register           */
       uint32_t RESERVED4[56];                                  
  __IO uint8_t  IP[240];                      /*!< Offset: 0x300  Interrupt Priority Register (8Bit wide) */
       uint32_t RESERVED5[644];                                 
  __O  uint32_t STIR;                         /*!< Offset: 0xE00  Software Trigger Interrupt Register     */
}  NVIC_Type;

以上定义中的uint32_t RESERVED0[24]，uint32_t RSERVED1[24]; ....是作什么用呢？权威指南没有找到说明。

可以理解为占用地址

正点原子
