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 re-calculating ECC/CRC by the downstream IPs in specific functional safety applications. See Port Descriptions for details on signal mapping.
In error scenarios, such as abrupt termination due to a soft reset, disabling the core while a packet transfer is in progress, a line buffer in a full condition, or when the word count of a received packet exceeds the actual payload, these sideband signals do not accurately report the ECC and CRC.
