Figure 136. 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.
