Program Suspend Status (Bit 2).
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 ‘1’ (Program/Erase Control-
ler inactive); after a Program/Erase Suspend com-
mand is issued the memory may still complete the
operation rather than entering the Suspend mode.
When the Program Suspend Status bit is ‘0’ the
Program/Erase Controller is active or has complet-
ed its operation; when the bit is ‘1’ a Program/
Erase Suspend command has been issued and
the memory is waiting for a Program/Erase Re-
sume command.
When a Program/Erase Resume command is is-
sued the Program Suspend Status bit returns to
‘0’.
Block Protection Status (Bit 1).
The Block Pro-
tection Status bit can be used to identify if the Pro-
gram or Block Erase operation has tried to modify
the contents of a protected block. When the Block
Protection Status bit is to ‘0’ no Program or Block
Erase operations have been attempted to protect-
ed blocks since the last Clear Status Register
command or hardware reset; when the Block Pro-
tection Status bit is ‘1’ a Program or Block Erase
operation has been attempted on a protected
block.
Once it is set to ‘1’ the Block Protection Status bit
can only be reset to ‘0’ by a Clear Status Register
command or a hardware reset. If it is set to ‘1’ it
should be reset before a new Program or Block
Erase command is issued, otherwise the new
command will appear to fail.
Using the A/A Mux Interface the Block Protection
Status bit is always ‘0’.
Reserved (Bit 0).
Bit 0 of the Status Register is
reserved. Its value should be masked.

Note: 1. For Program operations during Erase Suspend Bit 6 is ‘1’, otherwise Bit 6 is ‘0’.
