4.6.3. Avalon® -ST Pass-Through Interface

Packets with valid CRCs that are not recognized as being targeted to one of the implemented Logical layer modules are passed to the Avalon® -ST pass-through interface for processing by user logic.

The RapidIO IP core also provides hooks for user logic to report any error detected by a user-implemented Logical layer module attached to the Avalon® -ST pass-through interface.

The transmit side of the Avalon® -ST pass-through interface provides the gen_tx_error input signal that behaves essentially the same way as the atxerr input signal.

If Enable Avalon® -ST pass-through interface is enabled and at least one of the Data Messages options Source Operation and Destination Operation is turned on in the RapidIO parameter editor, the message passing error management input ports are added to the IP core to enable integrated error management.
