Description
Set/get the delay between the trigger occurring and the start of captured data. The delay is given
in units of trace periods (0x2505).
Note that the delay may be either positive or negative. A negative delay means that the data
captured will precede the trigger event by the specified number of cycles. Although any input value
is accepted, the number of samples preceding the trigger is limited to the length of the trace buffer
and the number (and size) of channels being captured.
