Number of Erase Block Regions within device
bit 7 to 0 = x = number of Erase Block Regions
Note:1. x = 0 means no erase blocking, i.e. the device erases at once in "bulk."
2. x specifies the number of regions within the device containing one or more
contiguous Erase Blocks of the same size.
For example, a 128KB device
(1Mb) having blocking of 16KB, 8KB, four 2KB, two 16KB, and one 64KB is
considered to have 5 Erase Block Regions.
Even though two regions both
contain 16KB blocks, the fact that they are not contiguous means they are sep-
arate Erase Block Regions.
3. By definition, symmetrically block devices have only one blocking region.

Erase Block Region Information
bit 31 to 16 = z, where the Erase Block(s) within this Region are (z) times 256 bytes in
size. The value z = 0 is used for 128 byte block size.
e.g. for 64KB block size, z = 0100h = 256 => 256 * 256 = 64K
bit 15 to 0 = y, where y+1 = Number of Erase Blocks of identical size within the Erase
Block Region:
e.g.
y = D15-D0 = FFFFh => y+1 = 64K blocks [maximum number]
y = 0 means no blocking (# blocks = y+1 = "1 block")
Note: y = 0 value must be used with number of block regions of one as indicated
by (x) = 0
