Parameter Transmission Process

Parameter data are exchanged between application and bus modules by means
of the Request-Response process. The application initiates an order with the help
of the toggle bit (TGL_MS != TGL_SM). The communications control register
(R57) then polls the module until the latter acknowledges the execution of the
order (TGL_SM == TGL_MS).
The possible orders to the parameterizing interface of the bus module are listed
in the following.
