SetPosition

This command is provided to the circuit by the LIN master

to drive one or two motors to a given absolute position. See

Positioning for more details.

The priority encoder table (See Priority Encoder)

describes the cases where a SetPositioncommand will

be ignored.

SetPosition corresponds to the following LIN write frames.

1. Two (2) Data bytes frame with a direct ID (type #3)

Checksum

Checksum over data

Where:

(*) According to parity computation

ID[5:0]: Dynamically allocated direct identifier. There should be as many dedicated identifiers to this SetPosition command

as there are stepper−motors connected to the LIN bus.

2. Four (4) Data bytes frame with general purpose identifier (type #1). Note: the dynamic ID allocation has to be

assigned to ‘General Purpose 4 Data bytes’ ROM pointer, i.e. ‘0001’.

3. Two (2) motors positioning frame with 0x3C identifier (type #4)
