Setting up ASTA UED LLRF for 180 Hz operation
ASTA UED derives its timing from LCLS EVG timing system.
LCLS EVG now has a new event code '165' for 180 Hz operation on beamcode 0 for LCLS.
Currently the masks have been setup to include timeslots 2,4 and 6 and exclude timeslots 1,3,5.
Each timeslot corresponds to 60 Hz. Thus the three included timeslots support 3*60Hz = 180 Hz operation.
Please do not change the Event modifier bits. Leave them as they are now.
