17.0 LIN Application Commands
17.1 Introduction
The LIN Master will have to use commands to manage the different application tasks the AMIS-30623 can feature. The commands
summary is given in the table below.
Table 34: Commands Summary
These commands are described hereafter, with their corresponding LIN frames. Refer to
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.

Description
Returns the actual position of the motor
Returns a complete status of the circuit
Returns the OTP memory content
Returns a short status of the circuit
Drives the motor to its secure position
Immediate motor stop
Actual position becomes the zero position
RAM content reset
Drives motor continuously
