各位大侠，小弟初学stm32，望大侠相助
stm32地址分配说明中比如TIM2地址是（0x4000 0000 - 0x4000 03FF ）TIM2定时器有1KB的地址空间，但是与TIM2有关的空间是：
__IO uint16_t CR1;
  uint16_t  RESERVED0;
  __IO uint16_t CR2;
  uint16_t  RESERVED1;
  __IO uint16_t SMCR;
  uint16_t  RESERVED2;
  __IO uint16_t DIER;
  uint16_t  RESERVED3;
  __IO uint16_t SR;
  uint16_t  RESERVED4;
  __IO uint16_t EGR;
  uint16_t  RESERVED5;
  __IO uint16_t CCMR1;
  uint16_t  RESERVED6;
  __IO uint16_t CCMR2;
  uint16_t  RESERVED7;
  __IO uint16_t CCER;
  uint16_t  RESERVED8;
  __IO uint16_t CNT;
  uint16_t  RESERVED9;
  __IO uint16_t PSC;
  uint16_t  RESERVED10;
  __IO uint16_t ARR;
  uint16_t  RESERVED11;
  __IO uint16_t RCR;
  uint16_t  RESERVED12;
  __IO uint16_t CCR1;
  uint16_t  RESERVED13;
  __IO uint16_t CCR2;
  uint16_t  RESERVED14;
  __IO uint16_t CCR3;
  uint16_t  RESERVED15;
  __IO uint16_t CCR4;
  uint16_t  RESERVED16;
  __IO uint16_t BDTR;
  uint16_t  RESERVED17;
  __IO uint16_t DCR;
  uint16_t  RESERVED18;
  __IO uint16_t DMAR;
  uint16_t  RESERVED19;
占80个字节，那还有多余的空间呢.?
