File: lin_dev.c

This file contains the user configurable system variable declarations for this 
LIN device.
 
This is a template file to be customized for each project.  The structures
associated with schedule tables are required only for Master nodes and the
variables for NAD, Supplier ID , Function ID etc. are required only for
Slave nodes (in systems using Master controlled node configuration).  The
remaining elements defined in this file are used for both Master and Slave
nodes.

Many of the structures associated with schedule tables are required only when
certain options have been enabled in "lin_dev.h".  For instance, the collision
resolution schedule tables are required only if ENABLE_EVENT_TRIGGERED has been
defined.  The tables associated with Sporadic frames are required only if
ENABLE_SPORADIC has been defined.

The specific values shown in the various structures such as schedule tables,
"LIN_id_table[]" and "LIN_signal_table[]" are shown as examples only.  Unless
otherwise noted (the first entry in "LIN_schedule_table[]" and the last entry
for "LIN_id_table[]", for instance), the entries shown in this file must be
replaced with equivalent entries as required by the LIN device being designed.
