5.2 Identifier Codes for Read Operation
Notes:
1. Bottom parameter device has its parameter blocks in the plane 0 (The lowest address).
2. DQ

is reserved for future implementation.
3. PCRC=Partition Configuration Register Code.
4. The address A

are shown in below table for reading the manufacturer, device, lock configuration, device
configuration code.
The address to read the identifier codes is dependent on the partition which is selected when writing the Read Identifier
Codes command (90H).
See Chapter 6. Partition Configuration Register Definition (P.15) for the partition configuration register.
