Description
This message is sent to the board to configure the operating mode of a LIU. All
configuration parameters must be supplied in the message, that is, it is not possible to
modify individual operating parameters in isolation. On receipt of the message, the
board first verifies that the fitted hardware options support the requested operating
mode and then initializes (or reinitializes) the LIU.
The confirmation message (if requested) indicates success with a status value of 0.
