WRITE STATUS REGISTER (WRSR): The WRSR instruction allows the user to select one of
four levels of protection. The AT25080A/160A/320A/640A is divided into four array segments.
One-quarter, one-half, or all of the memory segments can be protected. Any of the data within
any selected segment will therefore be read only. The block write protection levels and corre-
sponding status register control bits are shown in Table 8.
The three bits BP0, BP1, and WPEN are nonvolatile cells that have the same properties and
functions as the regular memory cells (e.g., WREN, tWC, RDSR).
The WRSR instruction also allows the user to enable or disable the write protect (WP) pin
through the use of the Write Protect Enable (WPEN) bit. Hardware write protection is enabled
when the WP pin is low and the WPEN bit is “1”. Hardware write protection is disabled when
either the WP pin is high or the WPEN bit is “0”. When the device is hardware write protected,
writes to the status register, including the block protect bits and the WPEN bit, and the block-
protected sections in the memory array are disabled. Writes are only allowed to sections of the
memory that are not block-protected.
NOTE: When the WPEN bit is hardware write protected, it cannot be changed back to “0” as
long as the WP pin is held low.
