Initiate
On receiving the Initiate command, the LRI2K sets the internal Initiate_Flag and sends back
a response. The command has to be issued in the Non Addressed mode only (Select_Flag
is reset to 0 and Address_Flag is reset to 0). If an error occurs, the LRI2K does not generate
any answer. The Initiate_Flag is reset after a power off of the LRI2K.
