Figure 154. 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 so that sequential Write Buffer and Read
Buffer commands access the same 512 bytes within the buffer.
