The MRS command to Non-MRS command delay, tMOD, is require for the DRAM to update the features except DLL
reset, and is the minimum time required from an MRS command to a non-MRS command excluding NOP and DES shown
as the following figure.
The mode register contents can be changed using the same command and timing requirements during normal operation
as long as the DRAM is in idle state, i.e., all banks are in the precharged state with tRP satisfied, all data bursts are
completed and CKE is high prior to writing into the mode register. If the RTT_NOM Feature is enabled in the Mode
Register prior and/or after an MRS Command, the ODT Signal must continuously be registered LOW ensuring RTT is in
an off State prior to the MRS command. The ODT Signal maybe registered high after tMOD has expired. If the RTT_NOM
Feature is disabled in the Mode Register prior and after an MRS command, the ODT Signal can be registered either LOW
or HIGH before, during and after the MRS command. The mode registers are divided into various fields depending on the
functionality and/or modes.
