Hi. I'M JK in RS Automation
I am preparing for Functional Safety certification with TuV for hardware based on RM44L920.
I am writing FMEDA of RM44L920 referring to the SPNU625 document.
I don't know the difference between 'Residual' and 'Latent'

Residual fault is a single-point fault, there is a safety mechanism, but the fault is not covered by the safety mechanism
Latent fault is a dual-point fault that can not be detected by a safety mechanism nor perceived by user.
