Stay Quiet
Command code = 0x02
On receiving the Stay Quiet command, the M24LR04E-R enters the Quiet State if no error
occurs, and does NOT send back a response. There is NO response to the Stay Quiet
command even if an error occurs.
When in the Quiet state:
The M24LR04E-R exits the Quiet State when:
Table 39.
The Stay Quiet command must always be executed in Addressed mode (Select_flag is reset
to 0 and Address_flag is set to 1).
Figure 53. Stay Quiet frame exchange between VCD and M24LR04E-R
When configured in the RF busy mode, the RF WIP/BUSY pin is tied to 0 during the Stay
Quiet command.
When configured in the RF write in progress mode, the RF WIP/BUSY pin remains in high-Z
state.

SOF
the M24LR04E-R does not process any request if the Inventory_flag is set,
the M24LR04E-R processes any Addressed request.
it is reset (power off),
