Sector Protection Register
The nonvolatile Sector Protection Register specifies which sectors are to be protected or unprotected with either the
software or hardware controlled protection methods. The Sector Protection Register contains 64 bytes of data, of which
byte locations 0 through 63 contain values that specify whether Sectors 0 through 63 will be protected or unprotected.
The Sector Protection Register is user modifiable and must be erased before it can be reprogrammed. Table 6-8
illustrates the format of the Sector Protection Register.
