32 KByte Flash Module (S12FTMRG32K1V1)
During the reset sequence, fields DPOPEN and DPS of the EEPROT register are loaded with the contents
of the EEPROM protection byte in the Flash configuration field at global address 0x3_FF0D located in
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.
