S32K344-How to implement [detect one bit errors without correction]

Hello

I saw the description in the following figure in the file [S32K3xx Safety Manual]. How is [detect one bit errors without correction] implemented?

BestRegards,

Simon

Could you point out which figure you have on your find?

In the RM, it is not explicitly defined which ECC SECDEC (single error correction, double error detection) variant is used, however it is clear that this code is capable to detect single bit error in the address.

Hi @davidtosenovjan

So what this means is that the ECC for data is 1-bit correction. The ECC for address is 1-bit detection without correction?

Yes, correct.
