STATE DIAGRAM
SYNCHRONOUS TRUTH TABLE
Notes:
1. "X" means don't care.
2. The rising edge of clock is symbolized by ↑
3. A continue deselect cycle can only be entered if a deselect cycle is executed first.
4. WE = L means Write operation in Write Truth Table.
5. Operation finally depends on status of asynchronous pins (ZZ and OE).
