Write Cycle No. 2(CE Controlled)
Notes
11. The internal write time of the memory is defined by the overlap of CE LOW and WE LOW. Both signals must be LOW to initiate a write and either signal can terminate
12. CY7C166 only: Data I/O will be high-impedance if OE = V
13. If CE goes HIGH simultaneously with WE HIGH, the output remains in a high-impedance state.

a write by going HIGH. The data input set-up and hold timing should be referenced to the rising edge of the signal that terminates the write.
