10.1.6 Status Register Protect (SRP)
The Status Register Protect (SRP) bit is a non-volatile read/write bit in status register (S7) that can be
used in conjunction with the Write Protect (/WP) pin to disable writes to status register. When the SRP
bit is set to a 0 state (factory default) the /WP pin has no control over status register. When the SRP
pin is set to a 1, the Write Status Register instruction is locked out while the /WP pin is low. When the
/WP pin is high the Write Status Register instruction is allowed.
