Bus operations

4.4
Data output
Data output bus operations read the data in the memory array, the status register, the
electronic signature, and the serial number.
Data is output when Chip Enable is Low, Write Enable is High, Address Latch Enable is Low,
and Command Latch Enable is Low.
The data is output sequentially using the Read Enable signal.
characteristics for operations for details of the timings requirements.
4.5
Write protect
Write protect bus operations protect the memory against program or erase operations.
When the Write Protect signal is Low the device does not accept program or erase
operations, therefore, the contents of the memory array cannot be altered. The Write Protect
signal is not latched by Write Enable to ensure protection, even during power-up.
4.6
Standby
When Chip Enable is High the memory enters standby mode: the device is deselected,
outputs are disabled and power consumption is reduced.
