3.5
The read identifier codes operation outputs the
manufacture code, device code, block status codes
for each block (see
Fig. 2
). Using the manufacture
and device codes, the system CPU can
automatically match the device with its proper
algorithms. The block status codes identify locked
or unlocked block setting and erase completed or
erase uncompleted condition.
Read Identifier Codes Operation

3.6
The query operation outputs the query structure.
Query database is stored in the 48-byte ROM.
Query structure allows system software to gain
critical information for controlling the flash
Query Operation
component. Query structures are always presented
on the lowest-order data output (DQ
0
-DQ
7
) only.
3.7
Writing commands to the CUI enable reading of
device data and identifier codes. They also control
inspection and clearing of the status register. When
V
CC =
V
CC1/2
and V
PP =
V
PPH1
, the CUI additionally
controls block erase, full chip erase, (multi)
word/byte write and block lock-bit configuration.
Write
The Block Erase command requires appropriate
command data and an address within the block to
be erased. The Word/Byte Write command requires
the command and address of the location to be
written. Set Block Lock-Bit command requires the
command and block address within the device
(Block Lock) to be locked. The Clear Block Lock-
Bits command requires the command and address
within the device.
The CUI does not occupy an addressable memory
location. It is written when WE# and CE# are
active. The address and data needed to execute a
command are latched on the rising edge of WE# or
CE# (whichever goes high first). Standard
microprocessor write timings are used.
Fig. 17
and
Fig. 18
illustrate WE# and CE#-controlled write
operations.
4 COMMAND DEFINITIONS
When the V
PP
voltage
≤
V
PPLK
, read operations
from the status register, identifier codes, query, or
blocks are enabled. Placing V
PPH1
on V
PP
enables
successful block erase, full chip erase, (multi)
word/byte write and block lock-bit configuration
operations.
Device operations are selected by writing specific
commands into the CUI.
Table 3
defines these
commands.
