The Write Status Register instruction (WRSR) allows the
user to write to the nonvolatile bits in the STATUS
register as shown in Table 2-2. See Figure 2-7 for the
WRSR timing sequence. Four levels of protection for the
array are selectable by writing to the appropriate bits in
the STATUS register. The user has the ability to write-
protect none, one, two or all four of the segments of the
array as shown in Table 2-3.
