This pin is used in conjunction with the WPEN bit in the status register to prohibit writes to the non-volatile bits in the status register. When WP is low and WPEN is high, writing to the non-volatile bits in the status reg- ister is disabled. All other operations function nor- mally. When WP is high, all functions, including writes to the non-volatile bits in the status register operate normally. If the WPEN bit is set, WP low during a sta- tus register write sequence will disable writing to the status register. If an internal write cycle has already begun, WP going low will have no effect on the write. The WP pin function is blocked when the WPEN bit in the status register is low. This allows the user to install the 25AA640/25LC640 in a system with WP pin grounded and still be able to write to the status regis- ter. The WP pin functions will be enabled when the WPEN bit is set high.
