Notes
Document Number: 001-06422 Rev. *I
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 15 address lines on the CY14B256L, only the lower 14 lines are used to control software modes.
3. I/O state depends on the state of OE. The I/O table shown is based on OE Low.
