nRF54L15 has RRAM with error correction codes (ECC) built in, with autocorrection.
I guess ECC errors could either happen due to a power loss during a write (when reading after reboot), or due to the word line has had too many writes, or due to aging. Correct me if I'm wrong.
In the data sheet there is a read-only register ECC.ERRORADDR that seems to be able to tell when we read an address where the content has been damaged, with the following documentation: "Address of the first ECC error that could not be corrected. The event ECCERROR is generated on ECC error. When this event is cleared, this register is updated on the next ECC error.". But there is no ECCERROR event documented? So how can we fulfill the second sentence? Something seems incomplete here in the documentation...
