When the ODD receives this command, it recognizes self-diagnostics.

When the ODD receives this command, it responds to the command regardless of the DRV bit value; this means that the drive is unit 0 or 1.

When the ODD is device 0 (master), its response after the command is received depends on whether device 1 (slave) is connected.

When no device 1 is connected

The ODD sets X'01' in the Error register and terminates the command.

When device 1 is connected

The ODD monitors the PDIAG- signal sent from device 1 for six seconds. If device 1 asserts the PDIAG- signal within this time, the ODD recognizes that the device 1 self-diagnostic test ends successfully. Otherwise, the ODD recognizes that the device 1 self-diagnostic test ended
