Data Input/Output: Bi-directional data bus.
Data Strobe: output with read data, input with write data. Edge-aligned with read data,
centered in write data. The data strobes DQS(n) may be used in single ended mode
or paired with optional complementary signals DQS(n) to provide differential pair
signaling to the system during both reads and writes. A control bit at EMR(1)[A10]
enables or disables all complementary data strobe signals.
DQS0 corresponds to the data on DQ0-DQ7
DQS1 corresponds to the data on DQ8-DQ15
DQS2 corresponds to the data on DQ16-DQ23
DQS3 corresponds to the data on DQ24-DQ31
