Write Status Register Instruction
See Figure 2-7 for the WRSR timing sequence.
( WRSR )
The Write Status Register instruction ( WRSR ) allows the
TABLE 2-3:
ARRAY PROTECTION
user to write to the nonvolatile bits in the STATUS reg-
ister as shown in Table 2-2. The user is able to select
one of four levels of protection for the array by writing
to the appropriate bits in the STATUS register. The
array is divided up into four segments. The user has the
ability to write-protect none, one, two or all four of the
segments of the array. The partitioning is controlled as
shown in Table 2-3.
The Write-Protect Enable (WPEN) bit is a nonvolatile
bit that is available as an enable bit for the WP pin. The

(WPEN) bit in the STATUS register control the
programmable hardware write-protect feature. Hard-
ware write protection is enabled when WP pin is low
and the WPEN bit is high. Hardware write protection is
disabled when either the WP pin is high or the WPEN
bit is low. When the chip is hardware write-protected,
only writes to nonvolatile bits in the STATUS register
are disabled. See Table 2-1 for a matrix of functionality
on the WPEN bit.
