Read Identifier Codes
The read identifier codes operation outputs the manufacturer code, device code, block lock
configuration codes for each block and the permanent lock configuration code (see Figure 4). Using
the manufacturer and device codes, the system CPU can automatically match the device with its
proper algorithms. The block lock and permanent lock configuration codes identify locked and
unlocked blocks and permanent lock-bit setting.
