As well as the 32 bytes of input and output data, an AS-Interface master
manages a large amount of configuration and parameter data. These data are
only required for setting up the AS-Interface circuit and for diagnostics and
therefore only have to be read or written occasionally.
In addition, the master supports slaves according to profile S-7.3 and S-7.4
and other multiplexing slaves, whereby large amounts of data can also occur.
Access is made to these non-time-critical data via the mailbox.
