... The device contains a user-enabled “boot block” protection feature. Two versions of the feature are available: the AT49F008A/8192A locates the boot block at lowest order addresses (“bottom boot”); the AT49F008AT/8192AT locates it at highest order addresses (“top boot”). To allow for simple in-system reprogrammability, the AT49F008A(T)/8192A(T) does not require high-input voltages for programming. Reading data out of the device is similar to reading from an EPROM ...

... This feature does not have to be activated; the boot block’s usage as a write-protected region is optional to the user. The address range of the boot block is 00000H to 03FFFH for the AT49F008A; FC000H to FFFFFH for the AT49F008AT; 00000H to 01FFFH for the AT49F8192A; and 7E000H to 7FFFFH for the AT49F8192AT. ...

If the data on I/O0 is low, the boot block can be programmed; if the data on I/O0 is high, the program lockout feature has been enabled and the block cannot be pro- grammed ...
