938 ; Function : void WriteBufferToFlash()

940 ; Description: Receives (writes) TransferLength sectors with length of 512 Bytes
941 ;
942 ; How it works:
943 ; This SW burns data into internal uPSD NOR FLASH. To save FLASH RW cycles,
944 ; it is looking for empty sector part you are burning in.
945 ; If the area is filled by 0xFF only, the sector part is assumed
946 ; to be erased before, so only data are written directly to the selected flash
947 ; sector.
948 ; If not, the sector is copied to the last flash sector #8,
949 ; erased afterwards and written back (with the updated data block).
