3.4.5. Data Messages

The Data Messages options indicate which, if any, data message operations are supported by user logic attached to the pass-through interface, which you must select on the Transport and Maintenance page.
Note: Turning on one or both of Source operation and Destination operation causes additional input ports to be added to the RapidIO IP core to support reporting of data-message related errors through the standard Error Management Extension registers.

Source Operation

Source operation, when turned on, sets the Data Message bit in the Source Operations CAR and indicates that this endpoint can issue Data Message request packets.

Destination Operation

Destination operation, when turned on, sets the Data Message bit in the Destination Operations CAR and indicates that this endpoint can process received Data Message request packets.
