(21) WRITE BUFFER (X'E8')
The host system can overwrite the contents of the sector buffer of the device with a desired data
pattern by issuing this command. Upon receipt of this command, the device sets the BSY bit of
the Status register. Then the device sets the DRQ bit of Status register and clears the BSY bit
when the device is ready to receive the data. After that, 512 bytes of data is transferred from the
host and the device writes the data to the sector buffer, then generates an interrupt.
