| 1 | Completion Code. Generic, plus following command specific: 80h = write-protected offset. Cannot complete write because one or more bytes of FRU data are to a write-protected offset in the FRU device. Note that an implementation may have allowed a ‘partial write’ of the data to occur. 81h = FRU device busy. Refer to the preceding table for the Read FRU Command for the description of this completion code. |
| 2 | Count written --- count is ‘1’ based |
