Example for the mode of operation
The following example shows the sequence in which ETS en-
tries are stored. The input channels are predened as follows:
DI 0 and DI1: time stamp at edge 0-1 enabled
DI 0 and DI1: time stamp at edge 1-0 enabled
The ETS entries available at time “t” are designated by the
green area in the diagram. ETS entries that are not (or no
longer) available have a grey background
New ETS entries are always entered starting
at address + 0 and already existing ETS en-
tries are each shifted by 4 bytes.
