Storage Area Flash (SAF) is enabled by clearing the SAFEN
bit. If enabled, the SAF block is placed at the end of memory
and spans 128 words. If the Storage Area Flash (SAF) is enabled,
the SAF area is not available for program execution.
Important: Storage Area Flash,
when enabled, may be used to store variables or other information, often in devices
without EEPROM; however, the SAF is accessed in the same manner as other Flash memory
areas.
