Table 134 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 0000h in
the Sector Count register is specified, then 65,536 sectors shall be transferred.
LBA Low Current LBA (7:0).
LBA Low Previous LBA (31:24).
LBA Mid Current LBA (15:8).
LBA Mid Previous LBA (39:32).
LBA High Current LBA (23:16).
LBA High Previous LBA (47:40).
