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 16-bytes of data,
of which byte locations 0 through 15 contain values that specify whether sectors 0 through 15 will be protected or
unprotected. The Sector Protection Register is user modifiable and must first be erased before it can be
reprogrammed.
