(ELIC registers MAAR, MADR, MACR)
Purpose of the switching task is to manage connections between time slots i.e. to
transfer data between memory locations. To every connection an identification is
assigned in order to make fast disconnection possible and to avoid hole handling within
the used connection table.
The connection information can be read back with the "Read Register Command (0x02)"
on page 11-17. The internal connection table (base address t.b.d.) contains consecutive
entries consisting of two consecutive 16-bit values each determining the source (first
word) and destination (second word) time slot address. The actual time slot can be
recalculated with the following table.
