16 KByte Flash Module (S12FTMRG16K1V1)
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.
Although the protection scheme is loaded from the Flash memory at global address 0x3_FF0C during the
reset sequence, it can be changed by the user. The P-Flash protection scheme can be used by applications
requiring reprogramming in single chip mode while providing as much protection as possible if
reprogramming is not required.

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 bit defines an unprotected address range as specified by the FPHS bits
1 When FPOPEN is set, the FPHDIS bit enables protection for the address range specified by the FPHS bits
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
Reserved Nonvolatile Bits — These RNV bits should remain in the erased state.
