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 exclude time slots 1,3 and 5 with the exclusion mask of 0x15 in Modifier 2.
Thus time slots 2,4 and 6 alone are active.
Each timeslot corresponds to 60 Hz. Thus the three active time slots support 3*60Hz = 180 Hz operation.
Please do not change the Event modifier bits. Leave them as they are now:
