The Write Sector(s) Ext command transfers one or more sectors from the host to the device,
then the data is written to the disk media.
The sectors are transferred through the Data Register 16 bits at a time.
If an uncorrectable error occurs, the write will be terminated at the failing sector.
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 will 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).
