DMB-DDU 2013 Header/Trailer bit definitions (some bits get repeated for bit error mitigation)
DMB_L1A: L1A Event Number, count from DMB
DMB_BXN: Bunch Crossing Number, count from DMB
TMB_DAV: non-zero indicates TMB data exists for this event
ALCT_DAV: non-zero indicates ALCT data exists for this event
CFEB_CLCT_SENT: indicates which CFEBs should have sent data to DMB
CFEB_DAV: indicates which CFEBs have sent data to DMB
CLCT-DAV-Mismatch: the CFEB_DAVs do not match the CLCTs sent
DMB_CRATE: peripheral crate ID from DMB
DMB_ID: board number of DMB
CFEB_MOVLP: the time sample for this event has multiple overlaps with samples from previous events
DMB-CFEB-Sync: bits used for DMB-CFEB synchronization check
ALCT_HALF: zero indicates that the ALCT FIFO on the DMB is half-full
TMB_HALF: zero indicates that the TMB FIFO on the DMB is half-full
CFEB_HALF: zero indicates that the CFEB FIFO on the DMB is half-full
DMB_L1PIPE: number of L1A Events backed-up in the DMB
ALCT_EMPTY: one indicates that the ALCT FIFO on the DMB is empty
TMB_EMPTY: one indicates that the TMB FIFO on the DMB is empty
CFEB_EMPTY: one indicates that the CFEB FIFO on the DMB is empty
ALCT_Start_Timeout: indicates that the start of ALCT data was not detected within the time-out period
TMB_Start_Timeout: indicates that the start of TMB data was not detected within the time-out period
CFEB_Start_Timeout: indicates that the start of CFEB data was not detected within the time-out period.
CFEB_End_Timeout: indicates that the end of CFEB data was not detected within the time-out period
ALCT_End_Timeout: indicates that the end of ALCT data was not detected within the time-out period
TMB_End_Timeout: indicates that the end of TMB data was not detected within the time-out period
ALCT_FULL: one indicates that the ALCT FIFO on the DMB is full
TMB_FULL: one indicates that the TMB FIFO on the DMB is full
CFEB_FULL: one indicates that the CFEB FIFO on the DMB is full
DMB_CRC: each DMB generates a 22-bit CRC that encompasses all CSC data from the first 9-code to the last F-code in the event
