Note:
1. CKE is high for all commands shown except Self Refresh.
2. BA0, BA1 select either the Base or the Extended Mode Register (BA0 = 0, BA1 = 0 selects Mode Register; BA0 = 1, BA1 = 0
selects Extended Mode Register; other combinations of BA0-BA1 are reserved; A0-A11 provide the op-code to be written to the
selected Mode Register.)
3. BA0-BA1 provide bank address and A0-A11 provide row address.
4. BA0, BA1 provide bank address; A0-A8
provide column address; A10 high enables the Auto Precharge feature
(non-persistent), A10 low disables the Auto Precharge feature.
5. A10 LOW: BA0, BA1 determine which bank is precharged.
A10 HIGH: all banks are precharged and BA0, BA1 are “Don’t Care.”
6. This command is auto refresh if CKE is high; Self Refresh if CKE is low.
7. Internal refresh counter controls row and bank addressing; all inputs and I/Os are “Don’t Care” except for CKE.
8. Applies only to read bursts with Auto Precharge disabled; this command is undefined (and should not be used) for read bursts
with Auto Precharge enabled or for write bursts
9. Deselect and NOP are functionally interchangeable.
