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