Table 3: C-BUS Address/Commands

In “C-BUS” protocol the MX806A is allocated Address/Command values 10H and 13H. C-BUS Command

Mode, Modulation and Volume assignments, and data requirements are given in Table 3 and illustrated in

Figure 5.

Commands and Data are only to be loaded in the group configurations detailed since the “C-BUS” interface

recognizes the first byte after Chip Select (logic “0”) as an Address/Command.

Function or Level control data, which is detailed in Table 4, Table 5, Table 6, and Table 7, is acted upon at

the end of the loaded instruction
