---help--- |
|
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. |
