5.5.2.14 IF Built-In Self-Test MSR (IF_BIST_MSR)
MSR Address
Type
Reset Value
IF_BIST_MSR may be used to run built-in self-test (BIST) on the IF Tag and Target RAMs, and to get an indication of
whether the BIST run passed or failed. There are separate BIST controllers for the Tag RAM and for the Target RAMs. A
MSR read of IF_BIST_MSR causes BIST to be run.
IF_BIST_MSR can only be run when the level-1 COF cache, the level-0 COF cache, and the return stack is disabled in the
IF_CONFIG MSR. If the COF cache is enabled, reading IF_BIST_MSR does not cause BIST to be run, and returns zero.
After BIST has been run by reading IF_BIST_MSR, the contents of the IF Tag RAMs is invalidated (cleared).
