1769-SM1 Channel 1 Status
The bits in the Channel Status word provide status information on the channel itself, where:
bit 00 Logic Status Valid - "1" indicates the Logic Status / Feedback values in the input image are valid
bit 01 Datlink A Out Valid - "1" indicates the Datalink A Out values in the input image are valid
bit 02 Datlink B Out Valid - "1" indicates the Datalink B Out values in the input image are valid
bit 03 Datlink C Out Valid - "1" indicates the Datalink C Out values in the input image are valid
bit 04 Datlink D Out Valid - "1" indicates the Datalink D Out values in the input image are valid
bit 05 not used
bit 06 Configuration Valid - "1" indicates if the configuration is valid (Channel 1 only)
bit 07 Configuration Error - "1" indicates if there is a configuration error (Channel 1 only)
bit 08 DPI/SCANport Port ID bit 0 -
bit 09 DPI/SCANport Port ID bit 1 - these bits indicate the Port # connected to on the Host
bit 10 DPI/SCANport Port ID bit 2 -
bit 11 SCANport Host Present - "1" indicates a SCANport Host is present
bit 12 DPI Host Present - "1" indicates a DPI Host is present
bit 13 32-bit Datalinks Present - "1" indicates 32-bit Datalinks are used
