When the Program Suspend Status bit is
‘
0
’
, the
Program/Erase Controller is active, or has com-
pleted 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 SR1).
The
Protection Status bit can be used to identify if the
Program or Erase operation has tried to modify the
contents of a protected block. When the Block Pro-
tection Status bit is to
‘
0
’
, no Program or Erase op-
erations have been attempted to protected blocks
Block
since the last Clear Status Register command or
hardware reset. When the Block Protection Status
bit is
‘
1
’
, a Program or 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 by a hardware reset. If it is set to
‘
1
’
,
it should be reset before a new Program or Erase
command is issued, otherwise the new command
will appear to have failed, too.
Using the A/A Mux Interface, the Block Protection
Status bit is always
‘
0
’
.
Reserved (Bit SR0).
Bit 0 of the Status Register
is reserved. Its value should be masked.
Table 14. Status Register Bits
Note: 1. For Program operations during Erase Suspend Bit SR6 is
‘
1
’
, otherwise Bit SR6 is
‘
0
’
.
