MCB1_CKE_n
D17
Clock enable: CKE HIGH activates, and CKE LOW deactivates, the
internal clock signals, input buffers, and output drivers. Taking CKE
LOW enables PRECHARGE power-down and SELF REFRESH
operations (all banks idle), or ACTIVE power-down (row active in any
bank). CKE is synchronous for all functions except SELF REFRESH
exit. All input buffers (except CKE) are disabled during power-down
and self refresh modes.

MCB1_CK
G16
Clock: CK is the system clock input. CK and CK# are differential
clock inputs. All address and control input signals are sampled on the
crossing of the positive edge of CK and the negative edge of CK#.
Input and output data is referenced to the crossing of CK and CK#
(both directions of the crossing).

Input data mask: DM is an input mask signal for write data. Input data
is masked when DM is sampled HIGH along with that input data
during a WRITE access. DM is sampled on both edges of DQS.
