Error information
(20) 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.
