3. PCR.15-11 and PCR.7-0 bits are reserved for future use.
Model No.: LRS1386
• 111 = There are four partitions in this configuration.
"001" in a bottom parameter device and "100" in a top
parameter device.
If these bits are read via the Read Identifier Codes/OTP
command, the device may output "1" or "0" on these bits.
Each plane corresponds to each partition respectively.
Dual work operation is available between any two
partitions.
