*1 : BA2 and A8, A10, and A13~A15 are RFU and must be programmed to 0 during MRS.
1.7 Mode Register MR1
The Mode Register MR1 stores the data for enabling of disabling the DLL, output driver strength, Rtt_Nom
impedance, additive latency, Write leveling enable, TDQS enable and Qoff. The Mode Register 1 is written by
asserting low on CS, RAS, CAS, WE, high on BA0 and low on BA1 and BA2, while controlling the states of
address pins according to Figure 7.

MR1[bit12]=1, all RTT_Nom settings are allowed; in
Write
MR1[bit12]=0, only RTT_Nom settings of RZQ/2,
RZQ4 and RZQ/6 are allowed.
*4: If RTT_Nomm is used during Writes, only the val-
ues RZQ/2,RZQ/4 and RZQ/6 are allowed.
