| * communication or command errors. |

| * Some PMBus chips respond with valid data when trying to read an unsupported |
| * register. For such chips, checking the status register is mandatory when |
| * trying to determine if a chip register exists or not. |
| * Other PMBus chips don't support the STATUS_CML register, or report |
| * communication errors for no explicable reason. For such chips, checking |
| * the status register must be disabled. |
