5. The following states must not be interrupted by any executable command; COMMAND INHIBIT or NOP commands must be  
applied on each positive clock edge during these states.  
Refreshing:  
Starts with registration of an AUTO REFRESH command and ends when tRC is met.  
Once tRC is met, the SDRAM will be in the all banks idle state.  
Accessing Mode  
Register:  
Starts with registration of a LOAD MODE REGISTER command and ends when tMRD  
has been met. Once tMRD is met, the SDRAM will be in the all banks idle state.  
Starts with registration of a PRECHARGE ALL command and ends when tRP is met.  
Once tRP is met, all banks will be in the idle state.  
Precharging All:  
6. All states and sequences not shown are illegal or reserved.  
7. Not bank-specific; requires that all banks are idle.  
8. May or may not be bank-specific; if all banks are to be precharged, all must be in a valid state for precharging.  
9. Not bank-specific; BURST TERMINATE affects the most recent READ or WRITE burst, regardless of bank..  
10. READs or WRITEs listed in the Command (Action) column include READs or WRITEs with AUTO PRECHARGE enabled and  
READs or WRITEs with AUTO PRECHARGE disabled.  
11. Does not affect the state of the bank and acts as a NOP to that bank.
