Device size = 2N Byte (12H = 18; 218 = 256 KByte)
Flash Device Interface description; 0001H = x16-only asynchronous interface
Maximum number of bytes in multi-byte write = 2N (00H = not supported)
Number of Erase Sector/Block sizes supported by device
Sector Information (y + 1 = Number of sectors; z x 256B = sector size)
y = 63 + 1 = 64 sectors (003FH = 63)
z = 16 x 256 Bytes = 4 KByte/sector (0010H = 16)
Block Information (y + 1 = Number of blocks; z x 256B = block size)
y = 3 + 1 = 4 blocks (0003H = 3)
z = 256 x 256 Bytes = 64 KByte/block (0100H = 256)
