Write Protect
(WP)
When the Write Protect pin (WP) is high, the write protection feature is enabled and operates as shown in
the following table. When the WP is low, write operation for all memory arrays are allowed. The read
operation is always activated irrespective of the WP pin status. WP should be fixed high or low during
operations since WP does not provide a latch function.
