Figure 65. Get System Info frame exchange between VCD and M24LR16E-R
When configured in the RF busy mode, the RF WIP/BUSY pin is tied to 0 from the SOF that
starts the Get System Info command to the end of the M24LR16E-R response.
When configured in the RF write in progress mode, the RF WIP/BUSY pin remains in high-Z
state.
