Fast Initiate
On receiving the Fast 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. The data
rate of the response is multiplied by 2.
The request contains:
Table 78.
The response contains:
