Set Up The Scheduler
“Scheduler” - a Granule Timing Module function
You have three sets of Mode Bits
- FEM Mode Bits
- initialize, run, fire on-board pulser
- LVL-1 Mode Bits
- tell LVL-1 to force an accept of correct crossing
- tell LVL-2 not to reject this event in ATPs
- PPG Mode bits
- fire external stimuli at chosen time delay
- light injected into PbSc, PbGl, RICH, TOF, BB
- charge injected into MuTR anode wires
You have to Time-(mis)Align the Mode Bits
- when you fire the laser and/or pulser
- when you fire the LVL-1 trigger
- when you reset charge-integrators
- how long these things last (if >1 tick)
Note: PPG has time-vernier for its outputs
