clean-up can either mean

packing files together toward the end of the file or, if file 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.
