LIN APPLICATION COMMANDS
Introduction
The LIN Master will have to use commands to manage the
different application tasks the AMIS−30621 can feature.
The commands summary is given in Table 29 below.

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.
