E0: End of Header, F0: Format: Always set to 00 for first AV header quadlet.
SID: Source ID, contains the node address of the sender of the isochronous data.
DBS: Size of the data blocks from which AV payload is constructed. The value 0 represents a length of 256 quadlets.
FN (Fraction Number): The encoding for the number of data blocks into which each source packet has been divided
(00 = 1, 01 = 2, 10 = 4, 11 = 8) by the transmitter of the packet.
QPC: Number of dummy quadlets appended to each source packet before it was divided into data blocks of the
specified size.
SPH: Indicates that a CYCTM based time stamp is inserted before each application packet (25 bits specified in the
IEC 61883 International Standard).
E1: End of Header, F1: Format: Should be set to 10 for second AV header quadlet.
FMT: Value inserted in the Format field.
FDF/SYT: If ‘‘EN FS” in Register IRXPKCTL (0x040) is set to ‘1’, then lower 16-bits are interpreted as SYT.
