1) You should activate the register protection of the safety related registers.
There are 2 possibilities to protect the registers either with hard or soft lock protection:
From the safety standpoint, the hard lock is a better choice because even if the software "gets crazy" it can't remove the lock.
2) Yes, the user can read the source of the last reset by looking at the status registers of the RGM, FES and DES.
