3.5
The read query operation outputs block status
information, CFI (Common Flash Interface) ID
string,
geometry information, and Intel-specific extended
query information.
3.6
The read identifier codes operation outputs the
manufacturer code,
configuration codes for each block, and the master
lock configuration code (see Figure 6). Using the
manufacturer and device codes, the system CPU
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.
3.7
Writing commands to the CUI enables reading of
device data, query, identifier codes, inspection and
clearing of the status register, and, when V
V
configuration.
The Block Erase command requires appropriate
command data and an address within the block to
be erased. The Byte/Word Program command
requires the command and address of the location
to be written. Set Master and Block Lock-Bit
commands require the command and address
within the device (Master Lock) or block 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 the device is enabled
and WE# is active. The address and data needed to
execute a command are latched on the rising edge
of WE# or the first edge of CE
disables the device (see Table 2, Chip Enable Truth
Table ). Standard microprocessor write timings are
used.
