I have some questions about RM48 and IEC 61508-2

user1411371

I have some questions about the relationship between choice of diagnostic methods of RM48x and IEC61508-2 Annex A table A 1.1.

The requirements for diagnostic coverage of CPU includes:

Coding and execution including flag register

Address calculation

Program counter, stack pointer

Register, internal RAM

Custom Diagnostics page of <Hercules FMEDA RM48x v1.0> line 2 includes " System register " and line 8 is " register bank". I don't know if these two meet the requirements of diagnosis ?

I think line 66, 67 memory cells and address decoder can meet the requirement of internal RAM.

Coding and execution including flag register

line 2 includes "excution", i don't know is this about excution of instructions ? How RM48x meets the requirements of coding and excution of instructions ?

I think line 2 "status and flag register" can meet the requirement of flag register.

Address calculation

How to satisfy diagnostic requirements for address calculation? I have not found diagnostics from documents

Program counter, stack pointer

Does system registers include "PC" and "SP" ? How to diagnose "PC" and "SP"

And I have a question of the Custom diagnostics Table ,what's the meaning the column of "Type" like "m", "pd" ?

Please forgive my poor English and I'm very grateful of you for answering my questions about RM48x and IEC 61508.

If the URL send to e-mail@wb, I should tell who manage the E-mail to forward the URL to my E-mail.
