flash memory may be providing status information instead of array data. Intel® Flash memories
allow proper initialization following a system reset through the use of the RP# input. In this
application, RP# is controlled by the same RESET# signal that resets the system CPU.

Read Query
The read query operation outputs block status information, CFI (Common Flash Interface) ID
string, system interface information, device geometry information, and Intel-specific extended
query information.
Read Identifier Codes
The read identifier codes operation outputs the manufacturer code, device code, block lock
configuration codes for each block, and the master lock configuration code (see Figure 5). 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.
