1. Applicable for both SLOW EXIT and FAST EXIT Precharge Power-down
2. tAOFPD and tAOF must be statisfied and outputs High-Z prior to T1; refer to ODT timing section for exact requirements
3. If the RTT_NOM feature was enabled in the mode register prior to entering Precharge power down mode, the ODT
signal must continuously be registered LOW ensuring RTT is in an off state. If the RTT_NOM feature was disabled in the mode register
prior to entering Precharge power down mode, RTT will remain in the off state. The ODT signal can be registered either LOW or HIGH in
this case.
