VCD
When configured in the RF busy mode, the RF WIP/BUSY pin is tied to 0 from the SOF that
starts the SetRstEHEn 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.
CheckEHEn
On receiving the CheckEHEn command, the M24LR16E-R reads the Control register and
sends back its 8-bit value in the response.
The Protocol_extension_flag should be set to 0 for the M24LR16E-R to operate correctly. If
the Protocol_extension_flag is at 1, the M24LR16E-R answers with an error code. The
Option_flag is not supported. The Inventory_flag must be set to 0.
