Number of identical partitions within the partition region
Partitions' erase block regions in this Partition Region.
1. x = 0 = no erase blocking; the Partition Region erases in
“bulk”
2. x specifies the number of erase block regions containing one
or more contiguous same-size erase blocks
3. Symmetrically blocked partitions have one blocking region
4. Partition size = (total blocks) x (individual block size)
Partition Region 2 Erase Block Region 1 Information
bits 0–15 = y, y+1 = number of identical-size erase blocks
bits 16–31 = z, region erase block(s) size are z x 256 bytes
