I2C读E2PROM单字节数据程序部分中，为何没有将数据送到pBuffer指向的地址？而是在多字节读的时候才有 *pBuffer = I2C_ReceiveData(I2C1)？？

while(NumByteToRead)
  {
if(NumByteToRead == 1)
{
   /* Disable Acknowledgement */
   I2C_AcknowledgeConfig(I2C1, DISABLE);

   /* Send STOP Condition */
   I2C_GenerateSTOP(I2C1, ENABLE);
}
/* Test on EV7 and clear it */
if(I2C_CheckEvent(I2C1, I2C_EVENT_MASTER_BYTE_RECEIVED))
{
   /* Read a byte from the EEPROM */
   *pBuffer = I2C_ReceiveData(I2C1);
   /* Point to the next location where the byte read will be saved */
   pBuffer++;

   /* Decrement the read bytes counter */
   NumByteToRead--;
}
  }
  /* Enable Acknowledgement to be ready for another reception */
  I2C_AcknowledgeConfig(I2C1, ENABLE);
}
