3.6.3.5. Data Cache Tag RAM
- Use a LOAD instruction from a data address to get the line in the cache. The line should be clean.
- Use a WRCTL instruction to set ECCINJ.DCTAG to INJS or INJD.
- Use a STORE instruction from a data address mapped to that line. The STORE instruction should hit in the data cache and write the tag RAM to set the dirty bit.
- The ECC error is injected when the tag RAM is written.
- Use a RDCTL instruction to ensure the value of ECCINJ.DCTAG is NOINJ. Before the RDCTL, use a FLUSHP instruction to avoid the RAW hazard on ECCINJ.
- Do another LOAD or STORE instruction to the same line.
- The ECC error should be triggered on this second LOAD/STORE instruction.
