Timing Waveform of Write Cycle No. 2 (CS Controlled Timing)
Timing Waveform of Write Cycle No. 3 (BHE, BLE Controlled Timing)
NOTES:
1. A write occurs during the overlap of a LOW CS, LOW BHE or BLE, and a LOW WE.
2. OE is continuously HIGH. If during a WE controlled write cycle OE is 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 or BHE and BLE LOW transition occurs simultaneously with or after the WE LOW transition, the outputs remain in a high-impedance state.
5. Transition is measured ±200mV from steady state.
