Token and frames
As patterns of the frames to be sent with a token, the following 6 types are
available.
1 When there is no cyclic data to be sent: Only a token is transmitted.
2 When there is only cyclic data: a token is transmitted together with cyclic
frame.
3 When there is only cyclic data and this cyclic data is sent in divided form:
Only the cyclic frames are transmitted and a token is attached to the last
cyclic frame.
4 When there is only message data: The message frame is transmitted and
then a token is transmitted.
5 When there are cyclic data and message data: The message frame is
transmitted and then the cyclic frame is transmitted together with a token.

divided form: The message frame is transmitted and then only the cyclic
frames are transmitted and a token is attached to the last frame.
