Chapter 21 128 Kbyte Flash Module (S12FTS128K1V1)
FPHDIS is cleared. The FPROT register is loaded from Flash address 0xFF0D during the reset sequence,
indicated by F in
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
defined by FPHS[1:0]
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

Protection Function for Program or Erase — It is possible using the FPOPEN bit to either select address
ranges to be protected using FPHDIS, FPLDIS, FPHS[1:0] and FPLS[1:0] or to select the same ranges to be
unprotected. When FPOPEN is set, FPxDIS enables the ranges to be protected, whereby clearing FPxDIS
enables protection for the range specified by the corresponding FPxS[1:0] bits. When FPOPEN is cleared,
FPxDIS defines unprotected ranges as specified by the corresponding FPxS[1:0] bits. In this case, setting
FPxDIS enables protection. Thus the effective polarity of the FPxDIS bits is swapped by the FPOPEN bit as
shown in
can remain unprotected for EEPROM emulation.
0 The FPHDIS and FPLDIS bits define Flash address ranges to be unprotected
1 The FPHDIS and FPLDIS bits define Flash address ranges 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
Flash Protection Lower Address Range Disable — The FPLDIS bit determines whether there is a
protected/unprotected sector in the lower space of the Flash address map.
0 Protection/unprotection enabled
1 Protection/unprotection disabled
Flash Protection Lower Address Size — The FPLS[1:0] bits determine the size of the protected/unprotected
sector as shown in
