(9) RECALIBRATE (X’1x’, x: X’0’ to X’F’)
This command performs the calibration. Upon receipt of this command, the
device sets BSY bit of the Status register and performs a calibration. When the
device completes the calibration, the device updates the Status register, clears the
BSY bit, and generates an interrupt.
This command can be issued in the LBA mode.
