See table below
Number of erase block regions (x) within device:
1. x = 0 means no erase blocking; the device erases in bulk
2. x specifies the number of device regions with one or
more contiguous same-size erase blocks.
3. Symmetrically blocked partitions have one blocking region
Flash device interface code assignment:
"n" such that n+1 specifies the bit field that represents the flash
device width capabilities as described in the table:
