Packet and Error Monitoring Signal for the Transport Layer
Table 5–13 shows the packet and error monitoring signal for the Transport layer. For
Physical layer packet and error monitoring signals, refer to Table 5–4 on page 5–3 .
Error Management Extension Signals
Table 5–14 to Table 5–16 describe the signals that are added when you enable the Error
Management Extensions registers in the RapidIO II parameter editor. All of these
signals are clocked in the sys_clk clock domain.
Table 5–13. Transport Layer Packet and Error Monitoring Signal
Signal Direction Description
transport_rx_packet_dropped Output
Pulsed high one Avalon clock cycle when a received packet is dropped by
the Transport layer. 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. For more information, refer to
“Transport
Layer” on page 4–70 .
Table 5–14. Error Setting Signals
Signal Direction Description
message_error_response_set Input
Support user logic in setting the corresponding fields in the
Logical/Transport Layer Error Detect
CSR at offset
0x308, For information about the register fields these signals can
set, refer to
Table 6–67 on page 6–43 ,
If your design does not use one or more of these signals, you
should tie the unused signals low.
