1) Active termination only applies to DQ, DQS, DQS and DM signals
2) When low, all register outputs will be driven low and the PLL clocks to the DRAM and registers will be set to low levels (the
3) CS1, ODT1 and CKE1 are used on dual rank modules only
4) Column address A11 is used on modules based on x4 organised 512Mb DDR2 components only.
