void FlashReadID(void)
{
	Select_Flash();	
	
	SPI_Flash_SendByte(0x90);
	SPI_Flash_SendByte(0x00);
	SPI_Flash_SendByte(0x00);
	SPI_Flash_SendByte(0x00);
	fac_id = SPI_Flash_ReadByte();	// BFH: 工程码SST
	dev_id = SPI_Flash_ReadByte();	// 41H: 器件型号SST25VF016B     
	
	NotSelect_Flash();	
}

Example #2

  	for(i = 0; i < 4; i++)
  	{
  		Data[i] = SPI_Flash_ReadByte();
  	}
  	NotSelect_Flash();	
}
