STM32F0xx_StdPeriph_Lib_。。。EEPROM24LC16读写的BUG

STM32F0的标准库的 uint32_t sEE_WritePage(uint8_t* pBuffer, uint16_t WriteAddr, uint8_t* NumByteToWrite)                         uint32_t sEE_ReadBuffer(uint8_t* pBuffer, uint16_t ReadAddr, uint16_t* NumByteToRead)
函数貌似有个BUG  其实也不一定说是BUG，至少是不方便，迷惑使用着吧，因为调用者不会老盯住sEEAddress去切换扇区啊。
就是写24LC16时地址0X100以前的数据可以读写
0X100以上的数据又把0X100以内的空间覆盖了
有人遇到过吗？
怎么解决的？

已经解决：

一，调用该函数之前改变sEEAddress
//#define sEE_HW_ADDRESS    0xA0 /* E2 = 0 */
// /*#define sEE_HW_ADDRESS    0xA2*/ /* E2 = 0 */
// /*#define sEE_HW_ADDRESS    0xA4*/ /* E2 = 0 */
// /*#define sEE_HW_ADDRESS    0xA6*/ /* E2 = 0 */
// /*#define sEE_HW_ADDRESS    0xA8*/ /* E2 = 0 *//
// /*#define sEE_HW_ADDRESS    0xAA*/ /* E2 = 0 *//
// /*#define sEE_HW_ADDRESS    0xAC*/ /* E2 = 0 *///
/*#define sEE_HW_ADDRESS    0xAE*/ /* E2 = 0 */  /* Get number of reload cycles */

二，函数内部改变sEEAddress
uint32_t sEE_ReadBuffer(uint8_t* pBuffer, uint16_t ReadAddr, uint16_t* NumByteToRead)
{
  uint32_t NumbOfSingle = 0, Count = 0, DataNum = 0, StartCom = 0;
  //还是这么改好：

      sEEAddress =0x00a0;
      sEEAddress +=(ReadAddr>>7)&0x000e;///////////////////20160811
...
}

uint32_t sEE_WritePage(uint8_t* pBuffer, uint16_t WriteAddr, uint8_t* NumByteToWrite)
{
  uint32_t DataNum = 0;
  sEE_WRITEALLOW();
//sEEAddress要改变 ，或者在调用该函数之前改变
//还是这么改好：
   sEEAddress =0x00a0;
      sEEAddress +=(WriteAddr>>7)&0x000e;///////////////////20160811


//       num=4;
//       test2[0] =0x10;
//       test2[1] =0x20;
//       test2[2] =0x30;
//       test2[3] =0x40;
//       test2[4] =0x50;
//       test2[5] =0x60;
//       sEE_WriteBuffer(test2, 0x0, 4);
//       test2[0] =0x11;

//       test2[2] =0x33;
//       test2[3] =0x44;
//       test2[4] =0x55;

//       sEE_WriteBuffer(test2, 0x100, 4);
