Notes:
1. DRAM has the option to drive leveling feedback on a prime DQ or all DQs. If feedback is driven only on one DQ, the
remaining DQs must be driven low, as shown in above Figure, and maintained at this state through out the leveling
procedure.
2. MRS: Load MR1 to enter write leveling mode.
3. NOP: NOP or Deselect.
4. Diff_DQS is the differential data strobe (DQS, DQS#). Timing reference points are the zero crossings. DQS is shown with
solid line, DQS# is shown with dotted line.
5. CK, CK#: CK is shown with solid dark line, where as CK# is drawn with dotted line.
6. DQS, DQS# needs to fulfill minimum pulse width requirements t DQSH (min) and t DQSL (min) as defined for regular Writes; the
max pulse width is system dependent.

T1 and CK - CK# high at T2]
