|
Clean-up can either mean packing files together toward the end of
|
|
the file or, if files are deleted at the end of the file, clean up
|
|
can simply mean erasing the end of FLASH memory so that it can be
|
|
re-used again. However, doing this can also harm the life of the
|
|
FLASH part because it can mean that the tail end of the FLASH is
|
|
re-used too often. This threshold determines if/when it is worth
|
|
erased the tail end of FLASH and making it available for re-use
|
|
(and possible over-wear). Default: 8192.
