• The table must be completed consecutively starting with the first entry. No gaps are
allowed between entries. If fewer than 64 M functions are defined, the remaining entries
must be pre-assigned with 0. All unavailable entries are at the end of the table.
• The decoding lists are channel-specific; decoding list DB 80 is intended for NC channel 1,
so that DB 95 accordingly belongs to NC channel 16.
• M decoding according to list is activated as a channel-specific function by means of MDs.
