RM0046 Flash Memory
Doc ID 16912 Rev 5 341/936
In the following sections, some non-volatile registers are described. Please notice that such
entities are not Flip-Flops, but locations of TestFlash or Shadow sectors with a special
meaning.
During the Flash initialization phase, the FPEC reads these non-volatile registers and
updates their related volatile registers. When the FPEC detects ECC double errors in these
special locations, it behaves in the following way:
● In case of a failing system locations (configurations, device options, redundancy,
EmbAlgo firmware), the initialization phase is interrupted and a Fatal Error is flagged.
● In case of failing user locations (protections, censorship, BIU, ...), the volatile registers
are filled with all 1s and the Flash initialization ends by clearing the MCR[PEG] bit.
