Thank you for the reply. Is there any documentation with more details about how to use them?

Does it mean that in case of correctable error, only ctrl_ecc_user_interupt will be high?

Is it possible that ctrl_ecc_user_interupt signal = 1 and ctrl_ecc_readdataerror = 0?

Are these bits sticky or will their values change for every read transaction?

If they are sticky, how will they be reset?

Thank you.
