Release 1.1 04/2016
Successful transmission of the parameter data to a 0942 UEM 783 module
is indicated by the MSG Instruction "Done". Any number of connected
modules can be configured with this command.
Bit 0 is used in status byte 1/control byte 1 in each case to report the status
and control parameterization.
To ensure that the modules adopt the new parameters in sync, the value of
bit 0 in control byte 1 of the BusHead must be inverted. The BusHead
indicates execution by inverting bit 0 in the BusHead's status byte 1.
