656 * TI - Task Interrupted, error after the command was acknowledged. It is

658 * TU - Task Unacked, command was transmitted but neither ACK (R_OK) nor NAK
659 * (R_ERR) was received due to loss of signal, broken connection, loss of
660 * dword sync or other reason. The application client should send the
661 * appropriate task query.
