Notes to Figure 7â11:
(1) These devices do not support Ã32/Ã36 mode.
(2) You can use the DQS/DQSn pins in some of the Ã4 groups as RUP/RDN pins. You cannot use a Ã4 group for memory interfaces if two pins in the
group are used as RUP and RDN pins for OCT calibration. You can still use the Ã16/Ã18 groups, including the Ã4 groups. However, there are
restrictions on using Ã8/Ã9 groups that include these Ã4 groups.
The DQS and DQSn pins are listed in the HardCopy IV pin tables as DQSXY and
DQSnXY, respectively, where X denotes the DQS/DQ grouping number, and Y
denotes whether the group is located on the top (T), bottom (B), left (L), or right (R)
side of the device.
The corresponding DQ pins are marked as DQXY, where X indicates which DQS
group the pins belong to and Y indicates whether the group is located on the top (T),
bottom (B), left (L), or right (R) side of the device. For example, DQS1L indicates a
DQS pin, located on the left side of the device, as shown in Figure 7â12. The DQ pins
belonging to that group are shown as DQ1L in the pin table.
