== Normal spill data ==

=== TAI Timecode ===

Timecode in TAI (International Atomic Time) scale is received by White Rabbit interface.

Global Event Number is received from Central Trigger Processor.

||<-32 rowclass="bits">2 - TAI Timestamp||
||31||30||29||28||27||26||25||24||23||22||21||20||19||18||17||16||15||14||13||12||11||10||9||8||7||6||5||4||3||2||1||0||
||<:-4>2||<:-28>TAI ns [27:0]||
||<:-4>2||<:-24>TAI seconds [23:0]||<:-2>TAI flags||<:-2>TAI ns [29:28]||
||<:-4>2||<:-12>Global Event Number [11:0]||<:-16>TAI seconds [39:24]||
||<:-4>2||<:-28>Global Event Number [39:12]||

TAI flags: 2 - timecode is valid, otherwise invalid.

=== Relative Timestamp ===
Relative timestamp is reset every spill.

Timestamp frequency: 83.333 MHz

||<-32 rowclass="bits">4 - Relative Timestamp||
||31||30||29||28||27||26||25||24||23||22||21||20||19||18||17||16||15||14||13||12||11||10||9||8||7||6||5||4||3||2||1||0||

=== Input Pulse Counters ===

||<-32 rowclass="bits">7 - input counters||
||31||30||29||28||27||26||25||24||23||22||21||20||19||18||17||16||15||14||13||12||11||10||9||8||7||6||5||4||3||2||1||0||
||<:-4>7||<:-28>unblocked input 0 count||
||<:-32>...||
||<:-4>7||<:-28>unblocked input 39 count ||

Counter number is its position in readout data. Counters are cleared at the beginning of spill and after every trigger.

== End of spill data ==

=== Logic State Counters ===

||<-32 rowclass="bits">0 - logic state counters, matched (excluding dead time)||
||31||30||29||28||27||26||25||24||23||22||21||20||19||18||17||16||15||14||13||12||11||10||9||8||7||6||5||4||3||2||1||0||
||<:-4>0||<:-28>matched and triggered logic state count||

||<-32 rowclass="bits">1 - logic state counters, all (triggered and dead time)||
||31||30||29||28||27||26||25||24||23||22||21||20||19||18||17||16||15||14||13||12||11||10||9||8||7||6||5||4||3||2||1||0||
||<:-4>1||<:-28>unblocked logic state count||

First logic state (number 0) is the trigger output. Counters are cleared at the beginning of spill.

== Trigger Word Bits ==

 . [0] - pulser 305 Hz
 . [7:1] - NIM7..NIM1 (NIM line)
 . [8] - LVDS1 (ST line)
 . [9] - LVDS6 (TQDC1 line)
 . [10] - LVDS10 (TQDC1 line)

== Input Counters Mapping ==
Input counter are enabled by TTC SPILL signal. The mapping between counter number, input channel and trigger logic line is following:

 . [0] - pulser
 . [1] - NIM1 (NIM line)
 . [2] - NIM2 (NIM line)
 . [3] - NIM3 (NIM line)
 . [4] - NIM4 (NIM line)
