2.3
Write Status Register (WRSR)
The WRSR instruction allows the user to select one of
four protection options 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 seg-
ments of the array. The partitioning is controlled as illus-
trated in Table 2-3.
See Figure 3-6 for WRSR timing sequence.
