Timing Waveform of Write Cycle No. 2 (CS Controlled Timing)
NOTES:
1. A write occurs during the overlap of a LOW CS and a LOW WE.
2. OE is continuously HIGH. During a WE controlled write cycle with OE LOW, t
3. During this period, I/O pins are in the output state, and input signals must not be applied.
4. If the CS LOW transition occurs simultaneously with or after the WE LOW transition, the outputs remain in a high impedance state. CS must be active during the t
5. Transition is measured ±200mV from steady state.
