Trying to alter data in any protected area in the P-Flash memory will result in a protection violation error
and the FPVIOL bit will be set in the FSTAT register. The block erase of a P-Flash block is not possible if
any of the P-Flash sectors contained in the same P-Flash block are protected.

Flash Protection Operation Enable — The FPOPEN bit determines the protection function for program or
erase operations as shown in
0 When FPOPEN is clear, the FPHDIS and FPLDIS bits define unprotected address ranges as specified by the
1 When FPOPEN is set, the FPHDIS and FPLDIS bits enable protection for the address range specified by the
Reserved Nonvolatile Bit — The RNV 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 a specific region of the P-Flash memory ending with global address 0x3_FFFF.
0 Protection/Unprotection enabled
1 Protection/Unprotection disabled
Flash Protection Higher Address Size — The FPHS bits determine the size of the protected/unprotected area
in P-Flash memory as shown
Flash Protection Lower Address Range Disable — The FPLDIS bit determines whether there is a
protected/unprotected area in a specific region of the P-Flash memory beginning with global address 0x3_8000.
