Table 132 Write Multiple Command (C5h)

The Write Multiple command transfers one or more sectors from the host to the device, then the
data is written to the disk media.
Command execution is identical to the Write Sectors command except that an interrupt is
generated for each block (as defined by the Set Multiple command) instead of for each sector.
The sectors are transferred through the Data Register 16 bits at a time.
