+/ which access method is used to the word data on the FAT volume.
+/
+/ 0: Byte-by-byte access. Always compatible with all platforms.
+/ 1: Word access. Do not choose this unless under both the following conditions.
+/
+/ * Address misaligned memory access is always allowed to ALL instructions.
+/ * Byte order on the memory is little-endian.
+/
+/ If it is the case, _WORD_ACCESS can also be set to 1 to reduce code size.
