a problem or not and decide which application strategy to adopt.
Important: While in shutdown mode, since there is no hold
current in the coils, the mechanical load can cause a step loss,
which indeed cannot be flagged by the AMIS−30622.
Note: The Priority Encoder is describing the management of
states and commands.

Warning: The application should limit the number of
consecutive GetFullStatus1 commands to try to get the
AMIS−30622 out of shutdown mode when this proves to be
unsuccessful, e.g. there is a permanent defect. The reliability
of the circuit could be altered since GetFullStatus1 attempts
to disable the protection of the H−bridges.
