LHF16Vll
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,,=2.7V-3.6V
VPP=VPPH1,2, the CUI additionally controls block erasure
and word/byte write.
The Block Erase command requires appropriate command
data and an address within the block to be erased. The
Word/Byte
address of the location to be written.
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
Figures 13 and 14 illustrate WE# and CE# controlled write
operations.
4 COMMAND DEFINITIONS
When the V,, voltage I VPPLK, Read operations from the
status register, identifier codes, or blocks are enabled.
Placing V,,,,,
and word/byte write operations.
Device
commands into the CUI. Table 4 defines these commands.
3.6 Write
operations
Write command requires the command and
on V,, enables successful block erase
are selected by writing
