When the lockout feature is activated, locked-out sectors will be READ only. The write protect pin will allow normal read/write operations when held high. When the WP is brought low and WPEN bit is “1”, all write operations to the status register are inhibited. WP going low while CS is still low will interrupt a write to the status register. If the internal status register write cycle has already been initiated, WP going low will have no effect on any write operation to the status register. The WP pin function is blocked when the WPEN bit in the status register is “0”. This will allow the user to install the AT25FS010 in a system with the WP pin tied to ground and still be able to write to the status register. All WP pin functions are enabled when the WPEN bit is set to “1

AT25FS010具有写保护功能，可以通过设置写保护个人识别码（WP）的方式来激活此功能。当写保护功能激活后，开启写保护功能的扇区将进入只读模式。在高级保护模式下，写保护个人识别码允许普通的读写操作。当WP级别为低且WPEN字节为“1”时，所有对状态寄存器的写操作将被禁止。在CS处于低状态时调低WP级别会造成对状态寄存器的写操作中断。如果内部状态寄存器的写循环已经启动，WP进入低级别不会对任何针对状态寄存器的写操作造成影响。当状态寄存器内的WPEN字节为“0”时，WP个人识别码功能将被屏蔽。在这种情况下，用户就可以安装AT25FS010于系统中，同时和WP个人识别码系统绑定，并且仍然能够对状态寄存器进行写操作。当WPEN字节设为“1”时，所有的WP个人识别码功能将被开启。
