+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.
