These commands are described hereafter, with their
corresponding LIN frames. Refer to LIN Frames for more
details on LIN frames, particularly for what concerns
dynamic assignment of identifiers. A color coding is used to

distinguish between master and slave parts within the frames
and to highlight dynamic identifiers. An example is shown
below.
Figure 26. Color Code Used in the Definition of LIN Frames
Usually, the AMIS−30623 makes use of dynamic identifiers for general−purpose 2, 4 or 8 bytes writing frames. If dynamic
identifiers are used for other purposes, this is acknowledged.
