The #WP pin provides inadvertent write protection. The #WP pin must be held high for any Erase or Program operation. The #WP pin is don care for all other operations. In typical use, the #WP pin ist connected to VSS with a standard pull-down resistor. #WP is then driven high whenever an Erase or Program operation is required. If the #WP pin is tied to VDD with a pull-up resistor, then all operations may occur and the write protection feature is disabled. The #WP pin has an internal pull-up and could remain unconnected when not used.

DATA POLLING: The AT29LV1024 features DATA polling to indicate the end of a program cycle. During a program cycle an attempted read of the last word loaded will result in the complement of the loaded data on I/O7 and I/O15. Once the program cycle has been completed, true data is valid on all outputs and the next cycle may begin. DATA polling may begin at any time during the pro- gram cycle.
