+The weat levelling component, together with FAT FS component, works with FAT FS sector size 4096
bytes which is standard size of the flash devices. In this mode the component has best perfomance,
but needs additional memoty in the RAM. To save internal memory the component has two additional modes
to work with sector size 512 bytes: Performance and Safety modes. In Performance mode by erase sector
operation data will be stored to the RAM, sector will be erased and then data will be stored
back to the flash. If by this operation power off situation will occure, the complete 4096 bytes
-will be lost. To prevent this the Safety mode was implemented. In dafety mode the data will be first

stored to the flash and after sector will be erased, will be stored back. If power off situation will
occure, after power on, the data will be recovered.
By default defined the sector size 512 bytes and Performance mode. To change these values please use
