Read Electronic Signature Command
The Read Electronic Signature command is used
to read the Manufacturer and Device Codes, the
Lock Status of the addressed bank, the Protection
Register, and the Configuration Register.
One Bus Write cycle is required to issue the Read
Electronic Signature command. Once a bank is in
Read Electronic Signature mode, subsequent
read operations in the same bank will output the
Manufacturer Code, the Device Code, the Lock
Status of the addressed bank, the Protection Reg-
ister, or the Configuration Register (see
Table 7.
).
The Read Electronic Signature command can be
issued at any time, even during program or erase
operations, except during Protection Register Pro-
gram operations. Dual operations between the Pa-
rameter bank and the Electronic Signature
locations are not allowed (see
Table 15., Dual Op-
eration Limitations
for details).
If a Read Electronic Signature command is issued
to a bank that is executing a program or erase op-
eration the bank will go into Read Electronic Sig-
nature mode. Subsequent Bus Read cycles will
output the Electronic Signature data and the Pro-
gram/Erase controller will continue to program or
erase in the background.
The Read Electronic Signature command will only
change the read mode of the addressed bank. The
read modes of other banks are not affected. Only
Asynchronous Read and Single Synchronous
Read operations should be used to read the Elec-
tronic Signature. A Read Array command is re-
quired to return the bank to Read Array mode.
Read CFI Query Command
The Read CFI Query command is used to read
data from the Common Flash Interface (CFI).
One Bus Write cycle is required to issue the Read
CFI Query command. Once a bank is in Read CFI
Query mode, subsequent Bus Read operations in
the same bank will output the contents of the Com-
mon Flash Interface.
The Read CFI Query command can be issued at
any time, even during program or erase opera-
tions.
If a Read CFI Query command is issued to a bank
that is executing a program or erase operation the
bank will go into Read CFI Query mode. Subse-
quent Bus Read cycles will output the CFI data
and the Program/Erase controller will continue to
program or erase in the background.
The Read CFI Query command will only change
the read mode of the addressed bank. The read
modes of other banks are not affected. Only Asyn-
chronous Read and Single Synchronous Read op-
erations should be used to read from the CFI. A
Read Array command is required to return the
bank to Read Array mode.
Dual operations between the Parameter Bank and
the CFI memory space are not allowed (see
Table
15., Dual Operation Limitations
for details).

Clear Status Register Command
The Clear Status Register command can be used
to reset (set to ‘0’) all error bits (SR1, 3, 4 and 5) in
the Status Register.
One Bus Write cycle is required to issue the Clear
Status Register command. The Clear Status Reg-
ister command does not affect the read mode of
the bank.
The error bits in the Status Register do not auto-
matically return to ‘0’ when a new command is is-
sued. The error bits in the Status Register should
be cleared before attempting a new program or
erase command.
Block Erase Command
The Block Erase command is used to erase a
block. It sets all the bits within the selected block
to ’1’. All previous data in the block is lost.
If the block is protected then the erase operation
will abort, the data in the block will not be changed
and the Status Register will output the error.
Two Bus Write cycles are required to issue the
command.
The first bus cycle sets up the Block Erase
command.
The second latches the block address and
starts the Program/Erase Controller.
If the second bus cycle is not the Block Erase Con-
firm code, Status Register bits SR4 and SR5 are
set and the command is aborted.
Once the command is issued the bank enters
Read Status Register mode and any read opera-
tion within the addressed bank will output the con-
tents of the Status Register. A Read Array
command is required to return the bank to Read
Array mode.
During Block Erase operations the bank contain-
ing the block being erased will only accept the
Read Array, Read Status Register, Read Electron-
ic Signature, Read CFI Query and the Program/
Erase Suspend command, all other commands
will be ignored.
The Block Erase operation aborts if Reset, RP,
goes to V
