9.9 Primary Instruction Cache Error Protection and Handling
Error Handling
All primary instruction cache errors are uncorrectable. If an error is detected, the instruction cache unit posts a Cache Error exception and initializes the D, TA, TS, and PIdx fields in the local CacheErr register (see Chapter 14, CacheErr Register (27), for more information). If an error is detected on the tag address or state array, the processor informs the external agent that an uncorrectable tag error was detected by asserting SysUncErr* for one SysClk cycle.
