14. WE must be HIGH during SRAM read cycles.
15. Device is continuously selected with CE, OE and BHE/BLE LOW.
16. Measured ±200 mV from steady state output voltage.
17. If WE is low when CE goes low, the outputs remain in the high impedance state.
18. HSB must remain HIGH during Read and Write cycles.
