Modes
The term mode refers to the mechanism for specifying, in a request, the set of LRI64
devices that shall answer to the request.
Addressed mode
When the Address_flag is set to 1 (Addressed mode), the request contains the unique ID
(UID) of the addressed LRI64 device (such as an LRI64 device). Any LRI64 receiving a
request in which the Address_flag is set to 1, compares the received Unique ID to its own
UID. If it matches, it execute the request (if possible) and returns a response to the VCD, as
specified by the command description. If it does not match, the LRI64 device 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 field. Any LRI64 device receiving a request in which the Address_flag is set to 0,
executes the request and returns a response to the VCD as specified by the command
description.
