You can use the .hexout to program blank enhanced configuration devices, update
portions of the flash memory (for example, a new configuration page), or both. This
file uses the Intel hexadecimal file format and contains 16 Mbits or 2 Mbytes of data.

To perform partial flash memory updates, select the relevant portions of the .hexout
using memory map information provided in the .map file.
Configuration data and processor space data could exist within the same physical
data block. In such cases, erasing the physical data block would affect both
configuration and processor data, requiring you to update both. You can avoid this
situation by storing application data starting from the next available whole data
block.
Enhanced configuration devices support an efficient compression algorithm that
compresses configuration data by 1.9× for typical designs, effectively doubling the
size of the device. To select the right density for enhanced configuration devices, you
should pre-calculate the total size of uncompressed configuration space.
By clicking Options (Convert Programming Files window), you can turn on the
Compression mode option in the Programming Object File Options window with pof
selected as the programming file type, as shown in
