Datasheet
Always clear the Status Register prior to resuming erase operations. This avoids Status Register
ambiguity when issuing commands during Erase Suspend. If a command sequence error occurs
during an erase-suspend state, the Status Register contains the command sequence error status
(SR[7,5,4] set). When the erase operation resumes and finishes, possible errors during the erase
operation cannot be detected via the Status Register because it contains the previous error status.
15.1.1
Clear Status Register
The Clear Status Register command clears the status register, leaving all partition read states
unchanged. It functions independent of V
PP
. The Write State Machine (WSM) sets and clears
SR[7,6,2,0], but it sets bits SR[5:3,1] without clearing them. The Status Register should be cleared
before starting a command sequence to avoid any ambiguity. A device reset also clears the Status
Register.
15.2
Read Device Identifier
The Read Device Identifier command instructs the addressed partition to output manufacturer
code, device identifier code, block-lock status, protection register data, or configuration register
data when that partition’s addresses are read (see
Section 9.2, “Device Commands” on page 47
for
details on issuing the Read Device Identifier command).
Table 17, “Device Identifier Information”
on page 77
and
Table 18, “Device ID codes” on page 77
show the address offsets and data values
for this device.
Issuing a Read Device Identifier command to a partition that is programming or erasing places that
partition in the Read Identifier state while the partition continues to program or erase in the
background.
5
Erase Status (ES)
0 = Erase successful.
1 = Erase fail or program sequence error when set with SR[4,7].
4
Program Status (PS)
0 = Program successful.
1 = Program fail or program sequence error when set with SR[5,7]
3
V
PP
Status (VPPS)
0 = VPP within acceptable limits during program or erase operation.
1 = VPP < VPPLK during program or erase operation.
2
Program Suspend Status
(PSS)
0 = Program suspend not in effect.
1 = Program suspend in effect.
1
Block-Locked Status
(BLS)
0 = Block not locked during program or erase.
1 = Block locked during program or erase; operation aborted.

(Non-buffered EFP operation. For Buffered EFP operation, see
Section 11.3, “Buffered Enhanced Factory Programming” on
page 60
).
0 = Program or erase operation in addressed partition.
1 = Program or erase operation in other partition.
0 = No active program or erase operations.
1 = Reserved.
