Chapter 27 512 Kbyte Flash Module (S12XFTX512K4V2)
27.3.2.5
The FPROT register defines which Flash sectors are protected against program or erase operations.
All bits in the FPROT register are readable and writable with restrictions (see
Protection
During the reset sequence, the FPROT register is loaded from the Flash Configuration Field at global
address 0x7F_FF0D. To change the Flash protection that will be loaded during the reset sequence, the
upper sector of the Flash memory must be unprotected, then the Flash Protect/Security byte located as
described in
Trying to alter data in any protected area in the Flash memory will result in a protection violation error and
the PVIOL flag will be set in the FSTAT register. The mass erase of a Flash block is not possible if any of
the Flash sectors contained in the Flash block are protected.

Flash Protection Open — The FPOPEN bit determines the protection function for program or erase as shown
in

1 The FPHDIS and FPLDIS bits enable protection for the address range specified by the corresponding
Reserved Nonvolatile Bit — The RNV[6] 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 Flash memory ending with global address 0x7F_FFFF.
