Table 127 Write Buffer Command (E8h)
The Write Buffer command transfers a sector of data from the host to the sector buffer of the
device. The sectors of data are transferred through the Data Register 16 bits at a time.
The Read Buffer and Write Buffer commands are synchronized such that sequential Write Buffer
and Read Buffer commands access the same 512 byte within the buffer.
