boot-block data protection
The 16K-byte boot block can be used to store key system data that is seldom changed in normal operation. Data
in this block can be secured by using different combinations of the reset/deep power-down pin (RP), the
write-protect pin (WP), and V
PP
supply levels. Table 2 shows a listing of these combinations.
