Table 184 Write Multiple Command (C5h)
The Write Multiple command transfers one or more sectors from the host to the device, and then the data is
written to the disk media.
Command execution is identical to the Write Sector(s) 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.
