Figure 128 Write Multiple EXT Command (39h)
The Write Multiple Ext 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 Sector(s) Ext 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.
Output Parameters To The Device
Sector Count Current
The number of continuous sectors to be transferred low order, bits (7:0)
Sector Count Previous
The number of continuous sectors to be transferred high order, bits (15:8). If zero is
specified in the Sector Count register, then 65,536 sectors shall be transferred.
