* Description : the intel nor flash 28F640J3 device command definitions.  
*               28F640J3 erase one sector at a time. It has no all-block erasure command.
*               Program only one byte or half-word at a time, from 1 to 0, NOT 0 to 1.
*               The number of read at a time is not confined.  
*
