1717 | * The adapter reports is present state through the phase. Only | |
1718 | * a single phase should be ever be set. Each phase can have multiple | |
1719 | * phase status bits to provide more detailed information about the | |

1721 | * status bits that are set when changing the phase are also valid | |
1722 | * for the new phase or be cleared out. Adapter software (monitor, | |
