Packet and Error Monitoring Signal for the Transport Layer
Table 5–22 shows the packet and error monitoring signal for the Transport layer. For
Physical layer packet and error monitoring signals, see Table 5–4 on page 5–2 .

Notes to Table 5–21 :
(1) All of these signals are included in the rio_data_messages conduit bundle in Qsys. This conduit bundle is enabled only in RapidIO variations
in which at least one of the Data Messages Source Operation or Destination Operation options is turned on.
(2) All of these input signals are sampled in the Avalon system clock domain.

Output
Pulsed high one Avalon clock cycle when a received
packet is dropped by the Transport layer. Received packets
are only dropped if the Avalon-ST pass-through interface
is not enabled in the variation. Examples of packets that
are dropped include packets that have an incorrect
destination ID, are of a type not supported by the selected
Logical layers, or have a transaction ID outside the range
used by the selected Logical layers.
