Note 1:
ODT turn on time min is when the device leaves high impedance and ODT resistance begins to turn on.
ODT turn on time max is when the ODT resistance is fully on. Both are measure from tAOND.
Note 2:
ODT turn off time min is when the device starts to turn off ODT resistance
ODT turn off time max is when the bus is in high impedance. Both are measured from tAOFD.
