In the ×9, ×18, and ×36 modes, a pair of complementary DQS pins (CQ and CQ#)
drives up to 9, 18, or 36 DQ pins, respectively, in the group, to support one, two, or
four parity bits and the corresponding data bits. The ×9, ×18, and ×36 modes support
the QDR II memory interface. CQ# is the inverted read-clock signal which is
connected to the complementary data strobe (DQS or CQ#) pin. You can use any
unused DQ pins as regular user I/O pins if they are not used as memory interface
signals.
