Once set High, the Program Status bit can only be
reset Low by a Clear Status Register command or
a hardware reset. If set High it should be reset be-
fore a new Program or Erase command is issued,
otherwise the new command will appear to fail.

Once set High, the V
set by a Clear Status Register command or a hard-
ware reset. If set High it should be reset before a
new Program, Erase, Block Protection or Block
Unprotection command is issued, otherwise the
new command will appear to fail.

If only the Program Status bit (SR4) is set
High, V
has applied the maximum number of pulses to
the byte and still failed to verify that the Write
Buffer has programmed correctly or that the
Block is protected.

If the failure is due to a program on a protected
block then Block Protection Status bit (SR1) is

Program Suspend Status (SR2). The Program
Suspend Status bit indicates that a Program oper-
ation has been suspended and is waiting to be re-
sumed. The Program Suspend Status should only
be considered valid when the Program/Erase
Controller Status bit is High (Program/Erase Con-
troller inactive); after a Program/Erase Suspend
command is issued the memory may still complete
the operation rather than entering the Suspend
mode.
When the Program Suspend Status bit is Low,
V
completed its operation; when the bit is High, V
a Program/Erase Suspend command has been is-
sued and the memory is waiting for a Program/
Erase Resume command.
When a Program/Erase Resume command is is-
sued the Program Suspend Status bit returns Low.
Block Protection Status (SR1). 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 protected block.
When the Block Protection Status bit is Low, V
no Program or Erase operations have been at-
tempted to protected blocks since the last Clear
Status Register command or hardware reset;
when the Block Protection Status bit is High, V
a Program (Program Status bit SR4 set High) or
Erase (Erase Status bit SR5 set High) operation
has been attempted on a protected 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 Program or Erase command is
issued, otherwise the new command will appear to
fail.
Reserved (SR0). Bit SR0 of the Status Register
is reserved. Its value should be masked.
