128 KByte Flash Module (S12FTMRG128K1V1)
P-Flash memory (see
EEPROM protection that will be loaded during the reset sequence, the P-Flash sector containing the
EEPROM protection byte must be unprotected, then the EEPROM protection byte must be programmed.
If a double bit fault is detected while reading the P-Flash phrase containing the EEPROM protection byte
during the reset sequence, the DPOPEN bit will be cleared and DPS bits will be set to leave the EEPROM
memory fully protected.
Trying to alter data in any protected area in the EEPROM memory will result in a protection violation error
and the FPVIOL bit will be set in the FSTAT register. Block erase of the EEPROM memory is not possible
if any of the EEPROM sectors are protected.

EEPROM Protection Control
0 Enables EEPROM memory protection from program and erase with protected address range defined by DPS
1 Disables EEPROM memory protection from program and erase
EEPROM Protection Size — The DPS[6:0] bits determine the size of the protected area in the EEPROM
memory, this size increase in step of 32 bytes, as shown in
bits
The Protection Size goes on enlarging in step of 32 bytes, for each DPS value
