FUNCTION TRUTH TABLE for CKE
ABBREVIATIONS:
H=High Level, L=Low Level, X=Don't Care
NOTES:
1. Low to High transition of CKE re-enable CLK and other inputs asynchronously.
A minimum setup time must be satisfied before any command except REFSX.
2. Power-Down and Self-Refresh can be entered only from the All Banks Idle State.
3. Must be legal command.
