Which PID will be recorded in register EPID of MPU module

[Yellen]

Hello, Team,

          We are trying to using MPU module in our design.  We read the Reference Manual of S32K1xx Series, but there is one doubt about the EPID in register Error Detail Register, slave port n (EDR0 - EDR4).

           It says the EPID records the process identifier of the faulting reference.  I wonder the "process identifier" would be PID in RGDn_WORD3  or the Current PID in MCM_PID?

"current_pid" is handled by Process ID register in MCM module.

Thanks for your reply.

But I want to know if the M0PE is set, what the EPID will be when a protection error happend.

Value from MCM_PID. PID in RGDn_WORD3 serves for process evaluation for region hit not for an error.
