Reserved system pattern names exist for the 54 trigger input signals. These pattern names can only be defined (assigned to). They cannot be used to form other patterns -- use regular named patterns for that purpose. The reserved system pattern names are:
TEM[i].TKR
TEM[i].CAL_LE
TEM[i].CAL_HE
TEM[i].BUSY
where i = 0, 1, 2, 3
FREE[j].CNO
FREE[j].VETO[k]
where j = 0, 1
k = 0..17
|
The values assigned to these patterns will be used to program the VME LAT COMM I/O Board FIFOs for playback.
For example, to program the VETO17 signal of FREE board 1 with 100 copies of the CLOCK_4 pattern defined in Section 2.1.1 one could write:
FREE[1].VETO[17]: -- Assign system pattern CLOCK_4(100) -- Repeat pattern CLOCK_4 100 times |
