This parameter sets the mode in which the Advanced Power Controller starts up when power is supplied.
The mode is identified by an index.

Options

Index

Start modes

Operation of the controller resumes with the same
modalities as the last state prior to shutdown. Digital
input states always take priority over other states.

Software shutdown.
