Number of program or erase operations allowed in a
partition:
Bits 0 - 3 = Number of simultaneous program opera-
tions.
Bits 4 - 7 = Number of simultaneous erase operations.
Simultaneous program or erase operations allowed
in other partitions while a partition in this region is
in program mode:
Bits 0 - 3 = Number of simultaneous program opera-
tions.

Simultaneous program or erase operations allowed
in other partitions while a partition in this region is
in erase mode:
Bits 0 - 3 = Number of simultaneous program opera-
tions.
Bits 4 - 7 = Number of simultaneous erase operations.
Types of erase block regions in this partition region:
x=0: No erase blocking; the partition region erases in
bulk.
x = Number of erase block regions with contiguous,
same-size erase blocks.
Symmetrically blocked partitions have one blocking
region.
Partition size = (Type 1 blocks) x (Type 1 block sizes) +
(Type 2 blocks) x (Type 2 block sizes) +...+ (Type n
blocks) x (Type n block sizes).
