(2) For the top side of the device, RUP, RDN, PLLCLKOUT3n, and PLLCLKOUT3p pins are shared with the DQ or DM pins to gain ×8 DQ group. You
cannot use these groups if you are using the RUP and RDN pins for on-chip termination (OCT) calibration or if you are using PLLCLKOUT3n
and PLLCLKOUT3p.
(3) There is no DM pin support for these groups.
(4) The RUP and RDN pins are shared with the DQ pins. You cannot use these groups if you are using the RUP and RDN pins for OCT calibration.
