NOTES:
1. The mode register may be loaded prior to the AUTO REFRESH cycles if desired.
2. If CS is HIGH at clock HIGH time, all commands applied are NOP, with CKE a “Don’t Care”.
3. JEDEC and PC100 specify three clocks
4. Outputs are guaranteed High-Z after command is issued.
5. A12 should be a LOW at t
