help
Specify the FAT sector size.
Sector size used by wear levelling library.
You can set default sector size or size that will
fit to the flash device sector size.
config WL_SECTOR_SIZE_FAT
With sector size set to 4096 bytes, wear levelling library is more
efficient. However if FAT filesystem is used on top of wear levelling
library, it will need more temporary storage: 4096 bytes for each
mounted filesystem and 4096 bytes for each opened file.
With sector size set to 512 bytes, wear levelling library will perform
more operations with flash memory, but less RAM will be used by FAT
filesystem library (512 bytes for the filesystem and 512 bytes for each
file opened).

Specify the mode to store data into the flash.
Specify the mode to store data into flash:
- In Performance mode a data will be stored to the RAM and then
stored back to the flash. Compared to the Safety mode, this operation is
faster, but if power will be lost when erase sector operation is in
progress, then the data from complete flash device sector will be lost.
- In Safety mode data from complete flash device sector will be read from
flash, modified, and then stored back to flash.
Compared to the Performance mode, this operation is slower, but if
power is lost during erase sector operation, then the data from full
flash device sector will not be lost.

In Performance mode a data will be stored to the RAM and then
stored back to the flash. Compare to the Safety mode, this operation
faster, but if by the erase sector operation power will be off, the
data from complete flash device sector will be lost.
