* BA2 and A13 are reserved for future use and must be set to 0 when programming the EMR(1).
*2 Mandatory for DDR2-1066
*3 When Adjust mode is issued, AL from previously set value must be applied.
*4 After setting to default, OCD calibration mode needs to be exited by settin gA9-A7 to 000.
*5 Output disabled – DQs, DQSs, DQSs, RDQS, RDQS. This feature is used in conjunction with DIMM IDD
measurements when IDDQ is not desired to be included.
*6 If RDQS is enabled, the DM function is disabled. RDQS is active for reads and do not care for writes.
