Notes:
1.
V = Valid X = Don’t Care L = Low level H = High level
2.
CKEn signal is input level when commands are issued.
3.
CKEn-1 signal is input level one clock cycle before the commands are issued.
4.
These are state designated by the BS0, BS1 signals.
5.
Power Down Mode can not entry in the burst cycle.
