APP0 to APP3

When Status/Control Stream is enabled, the status data received on the AXI Status Stream is stored into the APP fields of the End of Frame (EOF) Descriptor. For other S2MM descriptors with EOF = 0, the APP fields are set to zero by the Scatter Gather Engine.

Note: These fields are not updated by the Scatter Gather Engine if the Status/Control Fields are disabled.
