On Die Termination (ODT) Current
The ODT function adds additional current consumption
to the DDR2 SDRAM when enabled by the EMRS(1).
Depending on address bits A[6,2] in the EMRS(1) a

Parameter
Enabled ODT current per DQ
ODT is HIGH; Data Bus inputs are FLOATING
Active ODT current per DQ
ODT is HIGH; worst case of Data Bus inputs are
STABLE or SWITCHING.
Note: For power consumption calculations the ODT duty cycle has to be taken into account
