Parity fault handler improvements
The Parity Improvements feature provides the CPM the ability to collect and
report additional information on parity trap faults. Faults that parity audits
detect are improved to provide more information. This new information
includes the specified address of the fault and if the fault is in code or not in
code. This feature updates interfaces to the log (PM189), and trap (PM185)
reporting to include this new information. The Parity Improvements feature
depends on features AF5682 XPM Code Protection, and AF5680 XPM
Exception Traceback Enhancements.
Feature AN0741 provides the following parity fault handling improvements:
• unify the parity audit and parity trap handlers
• improve the data captured and saved by the new handler to
— use the information stored in the card state register (SR)
— localize the parity fault to a specified byte address
— perform hard/soft/intermittent fault categorization
— query to determine if the fault is in code
• update interfaces to the PM189 and PM185 log reporting systems, to
include the new information
