Read Identifier Codes
Operation
The read identifier codes operation outputs the
manufacturer code, device code, block lock
configuration codes for each block, and master lock
configuration code (see Figure 6). Using the
manufacturer and device codes, the system
software can automatically match the device with its
proper algorithms. The block lock and master lock
configuration codes identify locked and unlocked
blocks and master lock-bit setting.
3.6
Write
The CUI does not occupy an addressable memory
location. It is written when WE# and CE# are active
and OE# = V
IH
. 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.
Figure 18 illustrates a write operation.

COMMAND DEFINITIONS
When the V
PP
voltage
≤
V
PPLK
, read operations
from the status register, identifier codes, or blocks
are enabled. Placing V
PPH1/2
on V
PP
enables
successful block erase, program, and lock-bit
configuration operations.
Device operations are selected by writing specific
commands into the CUI. Table 3 defines these
commands.
