A similar command is used to set the multiplexer memory area end address:

With the MUX select LED command the sequencer can be simply connected to a single output (if more than one out-

put should be controlled by one sequencer see MUX tables - assignments of sequencers to channels (see page 49)):

With the MUX clear command the multiplexer tables are initialized (see page 49):

With the MUX next address command the MUX pointer can be moved down in the MUX table (see page 49):

address defined by MUX set start address; load the MUX with the content

of this memory address
