when the FPGA runs out of samples, and it's not between
bursts. See the "End of Burst flag" below.
+ D Dropped Packet Flag: Set in an IN packet if the FPGA
+ discarded an OUT packet because its timestamp had already
+ passed.
+
+ S Start of Burst Flag: Set in an OUT packet if the data is the
+ first segment of what is logically a continuous burst of data.
+ Must be zero in IN packets.
+
E End of Burst Flag: Set in an OUT packet if the data is the
last segment of what is logically a continuous burst of data.
Must be zero in IN packets. Underruns are not reported
when the FPGA runs out of samples between bursts.
- D Dropped Packet Flag: Set in an IN packet if the FPGA
- discarded an OUT packet because its timestamp had already
