Abstract
The invention relates to a data communication method which is based on a layer model, the layer model (1) having a media-independent interface (10), a memory (12) having one check bit (14), two check bits (16) or a plurality of check bits (14, 16) which are statically or dynamically set, at least one check bit (14, 16) being checked during a direct memory access process, and the contents of a memory cell being identified as entry to a function depending on whether or not the check bit (14, 16) has been set.

1-16. (canceled)
A data communication method based on a layer model having a media-independent interface, a memory having at least one check bit which is set statically or dynamically, comprising the steps of:
- checking the at least one check bit during a direct memory access process, and
- identifying a contents of a memory cell as being an entry to a function depending on whether or not the at least one check bit has been set.
A data converter comprising:
- an input and an output,
- a converter receiving at least one incoming data stream from the input, with the converter generating at an output at least one outgoing data stream different from the incoming data stream, and
- at least one function residing in the data converter and controlling conversion of the at least one incoming data stream in the converter, wherein the at least one function is selected depending on the at least one incoming data stream.
