| 13 | description: | |
| 14 | The OCM supports 64-bit wide ECC functionality to detect multi-bit errors |
| 15 | and recover from a single-bit memory fault.On a write, if all bytes are |
| 16 | being written, the ECC is generated and written into the ECC RAM along with |
| 17 | the write-data that is written into the data RAM. If one or more bytes are |
| 18 | not written, then the read operation results in an correctable error or |
| 19 | uncorrectable error. |
