Modes
The term “mode” refers to the mechanism used in a request to specify the set of LRI2Ks that
will answer the request.
Addressed mode
When the Address_flag is set to 1 (Addressed mode), the request contains the Unique ID
(UID) of the addressed LRI2K.
Any LRI2K that receives a request with the Address_flag set to 1 compares the received
Unique ID to its own. If it matches, then the LRI2K executes the request (if possible) and
returns a response to the VCD as specified in the command description.
If its UID does not match, then it remains silent.
Non-Addressed mode (general request)
When the Address_flag is set to 0 (Non-Addressed mode), the request does not contain a
Unique ID. Any LRI2K receiving a request with the Address_flag set to 0 executes it and
returns a response to the VCD as specified in the command description.
Select mode
When the Select_flag is set to 1 (Select mode), the request does not contain an LRI2K
Unique ID. The LRI2K in the Selected state that receives a request with the Select_flag set
to 1 executes it and returns a response to the VCD as specified in the command description.
Only LRI2Ks in the Selected state answer to a request where the Select Flag is set to 1.
The system design ensures in theory that only one LRI2K can be in the Select state at a
time.
