To change the Flash protection that will be loaded on reset, the upper sector of the Flash array must be
unprotected, then the Flash protection byte located at Flash address 0xFF0D must be written to.
A protected Flash sector is disabled by FPHDIS while the size of the protected sector is defined by
FPHS[1:0] in the FPROT register.
Trying to alter any of the protected areas will result in a protect violation error and the PVIOL flag will be
set in the FSTAT register (see
when protection is fully disabled by setting the FPOPEN and FPHDIS bits. An attempt to mass erase a
Flash array while protection is enabled will set the PVIOL flag in the FSTAT register.

Protection Function for Program or Erase — The FPOPEN bit is used to either select an address range to be
protected using the FPHDIS and FPHS[1:0] bits or to select the same address range to be unprotected as shown
in
0 The FPHDIS bit allows a Flash address range to be unprotected
1 The FPHDIS bit allows a Flash address range to be protected
Nonvolatile Flag Bit — The NV6 bit should remain in the erased state for future enhancements.
Flash Protection Higher Address Range Disable — The FPHDIS bit determines whether there is a
protected/unprotected area in the higher space of the Flash address map.
0 Protection/unprotection enabled
1 Protection/unprotection disabled
Flash Protection Higher Address Size — The FPHS[1:0] bits determine the size of the protected/unprotected
sector as shown in
Nonvolatile Flag Bits — The NV[2:0] bits should remain in the erased state for future enhancements.
