MCFxxxx: Coldfire Errata Updates adding SECF180, but update needs fixing

[TomE]

Freescale have just added SECF180 to the Errata documents for what looks like a wide range of parts, including MCF52xx, MCF53xx and MCF54xx. Searching for "SECF180" on Freescale's site finds MCF5208, MCF52277, MCF5445x, MCF53017, MCF5373, MCF5329 and PCN14325, which is a list of about 100 parts.

The Errata item is "SECF180: Spurious Interrupts Can Cause Incorrect Vector Fetch", Anyone abusing spurious interrupts should read this very carefully. Instead of generating vector 24 for a Spurious interrupt, the controllers can generate vectors 0 or 64.

The MCF5207 Errata looks to have been updated properly, but the MCF5329 and MCF5373 ones needs fixing and re-release.

SECF180 has been added to the body of the documents, and the revision numbers have been increased from "8" to "9" for the 29 and "7" to "8" for the 73.

Tables "Table 1. Summary of MCF532x Errata" haven't been updated with this change.

Tables "Table 3. Document Revision History" haven't been updated with this change.

I have forwarded this information and made sure that several change requests have been made on this so that the updates do happen on these errata sheets. Also for the ones that you have reported elsewhere in these forums. Thank you for bringing this to our attention, and I apologize for the problems in getting the errata updated in a timely fashion.

Thank you. I don't mind that the Table of Contents and the History Table missed getting updated, the important thing (for us Engineers) was that the contents in the errata for all these chips got updated promptly with the SECF180 details.

Thanks for trying with the others. You forwarded my report that the "Coldfire 3 Family Master Reference" document "COLDFIRE3UM.pdf" was corrupted in December 2009 and it is still broken and missing half the instructions in the instruction summary:
