Logical Divisions
In all enhanced configuration devices, configuration option bits are stored ranging
from word address 0x008000 to 0x00801F (byte address 0x010000 to 0x01003F).
These bits are used to enable various controller features such as configuration mode
selection, compression mode selection, and clock divider selection. In all enhanced
configuration devices, configuration data is stored starting from word address
location 0x008020 or byte address 0x010040. The ending address of configuration
space is not fixed and depends on the number and density of PLDs configured using
the enhanced configuration device as well as the number of pages. All remaining
address locations above the configuration space are available for processor
application code. The boot space spans addresses 0x000000 to 0x007FFF. Both boot
and application code spaces are intended for use by an external processor or PLD.

Physical Divisions
Conversely, physical divisions are flash data blocks that can be individually written to
and erased. For instance, the Sharp flash-based EPC16 device contains 16-Mbit Sharp
flash memory that is divided into 2 boot blocks, 6 parameter blocks, and 31 main data
blocks. These physical divisions vary from one flash memory or vendor to another
and must be considered if the external flash interface is used to erase or write flash
memory. These divisions are not significant if the interface is used as a read-only
interface after initial programming.
