Offset Length
Description
Number of erase block regions within device:
1. x = 0 means no erase blocking; the device erases in “bulk”
2. x specifies the number of device or partition regions with 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)
