Modes
The term “mode” refers to the mechanism used in a request to specify the set of
M24LR04E-Rs that answers the request.
Addressed mode
When the Address_flag is set to 1 (Addressed mode), the request contains the Unique ID
(UID) of the addressed M24LR04E-R.
Any M24LR04E-R that receives a request with the Address_flag set to 1 compares the
received Unique ID to its own. If it matches, then the M24LR04E-R executes the request (if
possible) and returns a response to the VCD as specified in the command description.
If the UID does not match, then it remains silent.
Non-addressed mode (general request)
When the Address_flag is cleared to 0 (Non-Addressed mode), the request does not contain
a Unique ID. Any M24LR04E-R receiving a request with the Address_flag cleared 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 M24LR04E-
R Unique ID. The M24LR04E-R 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 M24LR04E-Rs in the Selected state answer a request where the Select_flag set to 1.
The system design ensures in theory that only one M24LR04E-R can be in the Select state
at a time.
