Figure 86. Read Buffer Command (E4h)
The Read Buffer command transfers a sector of data from the sector buffer of device to the host.
The sector is transferred through the Data Register 16 bits at a time.
The sector transferred will be from the same part of the buffer written to by the last Write Buffer com-
mand. The contents of the sector may be different if any reads or writes have occurred since the Write
Buffer command was issued.
