PCR.15-11 = RESERVED FOR FUTURE
ENHANCEMENTS (R)
PCR.10-8 = PARTITION CONFIGURATION (PC2-0)
000 = No partitioning. Dual Work is not allowed.
001 = Plane1-3 are merged into one partition.
(default in a bottom parameter device)
010 = Plane 0-1 and Plane2-3 are merged into one
partition respectively.
100 = Plane 0-2 are merged into one partition.
(default in a top parameter device)
011 = Plane 2-3 are merged into one partition. There are
three partitions in this configuration. Dual work
operation is available between any two partitions.
110 = Plane 0-1 are merged into one partition. There are
three partitions in this configuration. Dual work
operation is available between any two partitions.
101 = Plane 1-2 are merged into one partition. There are
three partitions in this configuration. Dual work
operation is available between any two partitions.
111 = There are four partitions in this configuration.
Each plane corresponds to each partition
respectively. Dual work operation is available
between any two partitions.
PCR.7-0 =
RESERVED FOR FUTURE ENHANCEMENTS (R)
Notes:
After power-up or device reset, PCR10-8 (PC2-0) is set to
“001” in a bottom parameter device and “100” in a top
parameter device.
See the table below for more details.
PCR.15-11 and PCR.7-0 are reserved for future use and should
be masked out when polling the partition configuration
register.
