Table 3.
As a second level of protection, the Write Protect signal (applied on the W/V
PP
pin) can
freeze the Status Register in a read-only mode. In this mode, the Block Protect bits (BP2,
BP1, BP0) and the Status Register Write Disable bit (SRWD) are protected. For more
details, see
Section 6.5: Write Status Register (WRSR)
