Asynchronous ODT mode is available when the DRAM runs in DLL on mode and when
either R
charged power-down standby (via MR0[12]). Additionally, ODT operates asynchronous-
ly when the DLL is synchronizing after being reset. See Power-Down Mode (page 169)
for definition and guidance over power-down details.
In asynchronous ODT timing mode, the internal ODT command is not delayed by AL
relative to the external ODT command. In asynchronous ODT mode, ODT controls R
by analog time. The timing parameters
