* Description : the serial flash m25p64 page size, command definitions.   
*               m25p64 erase one sector or all the block at a time.
*               The page program instruction allows up to 256 bytes to be programmed.
*               Before the Erase, Program & Write Status Register instruction, Write Enable instruction 
*               should be applied.
*               The read instruction can read as many as possible bytes at a time.
* Date        : Dec 1, 2005
