The TMC211 is set into motor shutdown mode as soon as one of the following conditions occur:
•
•
•
•
During motor shutdown the following actions are performed by the main controller:
•
•
The LIN interface remains active during motor shutdown. To leave the motor shutdown state the
following conditions must be true:
•
•
Leaving the motor shutdown state initiates the following
