CE Chip Enable Input CE is active LOW. It must be active to read from or write to the device. If chip enable is not active, the device is deselected and is in a standby power mode. The I/O pins will be in the high-impedance state when deselected. OE Output Enable Input The output enable input is active LOW. When OE is Low with CE Low and WE High, data will be presented on the I/O pins. The I/O pins will be in the high ...
