1. Bottom parameter device has its parameter blocks in the plane 0 (The lowest address).
2. DQ
3. PCRC=Partition Configuration Register Code.
4. The address A
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.
