5.1 English

Sideband signals of AXI4-Stream interface [Include/Exclude Video Format Bridge and Embedded non-image interface] report ECC and CRC data received from the source [sensor] to downstream IPs. This allows to re-calculate ECC/CRC by the downstream IPs in certain functional safety applications. See Port Descriptions for details on signal mapping.

In error scenarios like abrupt termination due to soft reset, disabling the core while packet transfer in progress, line buffer in full condition, word count of received packet is greater than the actual payload, these sideband signals do not report the correct ECC and CRC.
