Preset All
Turns on Trace 1, and blanks all other traces. This operation does not affect the trace
type, trace detector, and other states.
Clear All
Clears all traces. All the trace data will be set to the minimum trace value (except the
case that the trace is in Min Hold state). When the trace is in Min Hold state, the trace
data will be set to the maximum trace value. That is, even if you turn off the trace
update, the trace data will be updated after you perform the "Clear All" operation.
