The Response contains:
Table 91.
During an Inventory process, if the VCD does not receive an RF M24LR04E-R response, it
waits for a time t

When configured in the RF busy mode, the RF WIP/BUSY pin is driven to 0 from the SOF
starting the inventory command to the end of the M24LR04E-R response.If the M24LR04E-
R does not receive the corresponding slot marker, the RF WIP/BUSY pin remains at 0 till the
next RF power-off.
When configured in the RF write in progress mode, the RF WIP/BUSY pin remains in high-Z
state.
