 * The following two #defines must be set identically for the can-lib and
 * your application program. They control the underlying CAN struct. If the
 * settings disagree, the underlying CAN struct will be broken, with
 * unpredictable results.
 * If can.h detects that any of the #defines is not defined, it will set them
 * to the default values shown here, so it is in your own interest to have a
 * consistent setting. Ommiting the #defines in both can-lib and application
 * program will apply the defaults in a consistent way too.
