Non-Volatile Protection
The device can be software protected against erroneous or malicious program or erase operations by utilizing the Non-
Volatile Protection feature of the device. Non-Volatile Protection can be enabled or disabled by using the Write Status
Register command to change the value of the Protection (CMP, SEC, TB, BP2, BP1, BP0) bits in the Status Register.
The following table outlines the states of the Protection bits and the associated protection area
.
