Where are the parity bits for memory protection stored? Is it possible to access them?

Hello Community,

I am using STM32L432KC. This MCU has parity bit protection for 16Kb of SRAM2 memory.

Where are the memory's parity bits stored? Is it possible to access them?

In the manuals explanations are quite short, just describing basic stuff. Are there any detailed explanations about SRAM memories with parity bits protection ? 

Best regards.

No, parity is only handled internal. No official way to access these bits.

Thanks Uwe for the fast answer...do you know maybe if there is another MCUs from STM family with this feature.

The array is presumably widened to accommodate the extend bit line.

You might want to probe your local FAE for details/specifics.

I will definitely try, thanks for the advice !
