216468 - REG_PROT query

[RandyKrakora]

Customer is Ford.

AOU 216468 and 25593:

to fulfill static configuration registers check via : REG_PROT, XRDC and MMU.

we have way of fulfilling static configuration registers check of MSCM static registers by periodic interrupt monitoring .

Is it sufficient to fulfill the given AoUs or do we need to implement REG_PROT for individual registers as well.

if yes, could you please help us with the registers which needs to be protected/verified by REG_PROT.

Note: As discussed, only MSCM configuration registers are leading to single point failures.

Hi Randy,

Static configuration register check is sufficient if done periodically within FTTI. This solution will detect failure.

REG PROT can be used to prevent the failure from happening, what they are going is actually what we recommend for newer device.
