2.7.5
The auto mode of the ICC and ISAC-S TE is only applicable for the states 7 and 8 of the LAPD
protocol. All other states (1 to 6) have to be performed in Non-Auto Mode (NAM). Therefore
this documentation gives an overview of how the device reacts in the states 7 and 8, which
reactions require software programming and which are done by the hardware itself, when
interrupts and status register contents are set or change. The necessary software actions are
also detailed in terms of command or mode register access.
The description is based on the SDL diagrams of the ETSI TS 46-20 dated 1989.
The diagrams are only annotated by documentary signs or texts (mostly register descriptions)
and can therefore easily be interpreted by anyone familiar with the SDL description of LAPD.
All deviations that occur are specially marked and the impossible actions, paths etc. are
crossed out.
To get acquainted with this documentation, first read through the legend-description and the
additional general considerations, then start with the diagrams, referring to the legend and the
register description in the Technical Manual if necessary.
We hope you will profit from this documentation and use our software-saving auto-mode.

Documentation of the Auto Mode
Legend of the Auto-Mode Documentation
In the auto-mode the device processes all subsequent state
transitions branchings etc. up to the next symbol.
In the auto-mode the device does not process the state transitions,
branchings etc. Within the path appropriate directions are given with
which the software can accomplish the required action.
A path cannot be implemented and no software or hardware action
can change this. These paths are either optional or only applicable for
window-size > 1.
