Note: If the segments have different clock frequencies, there are some restrictions on signal output, i.e. seamless switching between segments is only possible, if all segments have the same clock frequency.

One marker element 'mx' consists of 4 bit, which are assigned to the 4 possible marker lines of the instrument (one bit per marker line).
