| * CVA6 provides two custom CSRs for cache management: |
| * CSR 7C1 controls the data cache, CSR 7C0 controls the instruction cache. |
| * The least significant bit of the CSRs can be written to enable or disable the cache. |
| * Writing a value of 1 means enabling the cache, writing 0 disables it. |
| * After reset, both caches are enabled by default. |
