    gram/Erase Controller Status bit is High (Program/
    Erase Controller inactive). Bit 2 is set within 5μs of
    the Program/Erase Suspend command being is-
    sued therefore the memory may still complete the
    operation rather than entering the Suspend mode.
    When a Program/Erase Resume command is is-
    sued the Program Suspend Status bit returns Low.
    Block Protection Status (Bit 1).
    The Block Pro-
    tection Status bit can be used to identify if a Pro-
    gram or Erase operation has tried to modify the
    contents of a locked block.
    When the Block Protection Status bit is High (set
    to ‘1’), a Program or Erase operation has been at-
    tempted on a locked block.
    Once set High, the Block Protection Status bit can
    only be reset Low by a Clear Status Register com-
    mand or a hardware reset. If set High it should be
    reset before a new command is issued, otherwise
    the
