Notes
Document Number: 001-06401 Rev. *G
1. The six consecutive address locations are in the order listed. WE is HIGH during all six cycles to enable a nonvolatile cycle.
2. While there are 17 address lines on the CY14B101K, only the lower 16 lines are used to control software modes.
3. O state depends on the state of OE. The IO table shown is based on OE Low.
