Detailed Description

The header that is inserted by the DAQ firmware (on the Bittware) or emulated by software (on the ZCU)

This needs to be its own class since it is used in both MultiSamleECONDEventPacket::from and MultiSampleECONDEventPacket::read

4b vers | 10b ECON ID | 5b il1a | S | 12b length

• vers is the format version
• ECOND ID is what it was configured in the software to be
• il1a is the index of the sample relative to this event
• S signals if this is the sample of interest (1) or not (0)
• length is the total length of this link subpacket NOT including this header

is_ending_trailer()

bool pflib::packing::DAQHeader::is_ending_trailer ( ) const

inline

A special form of this DAQ header is used to signal the end of a multi-sample sequence.

Both i_l1a and econd_id are set to their maximum values.
