With the variables “glob_speed_mod” and “low_speed_sel” there is a wide variety to modify
the ARINC429 speed. The selection for these values are valid for all channels of the board.
The selection of high- or low-speed has to be done for each channel (see function
Api429CmdTmrIntCon). The exact selectable values for the speed are shown in the
following table.
