TraceTrig
TraceTrig
The TraceTrig instruction generates a trigger for data tracing.
The TraceTrig instruction generates a trigger for data tracing. It does not matter whether the trigger con-
ditions that were set from the Sysmac Studio have been met. Sampling starts if data tracing is in
progress for trace number TraceNo when the instruction is executed.
The following figure shows a programming example. Here, a data trace trigger is generated for trace
number 1.
