word is framed with an accompanying word type indicator: idle/hold (no
data), data (more to come, data in this timeslot), start data (first
word of transaction ready, possibly the only word), last data (data in
this timeslot). The high level protocol is then sequences of
transaction words, of the form:

<br>

( ((Start multi (Hold* Data*)* Last) | (Start single) | Idle )*

<br>

The format of the transaction words within, the transaction header word, is:
