Word 47:
maximum number of sectors that can be read or written per interrupt using
the Read Multiple or Write Multiple commands.
Word 48: Double Word Support. This field indicates this product will not
support double word transfers.
Word 49: Capabilities. This field indicates if this product supports DMA Data
transfers and LBA mode. All SanDisk products support LBA mode.
