Fast Write Dynamic Configuration
On receiving the Fast Write Dynamic Configuration command, the ST25DV updates the Dynamic register
addressed by the pointer.
The Option_flag is not supported. The Inventory_flag must be set to 0.
The data rate of the response is multiplied by 2 compared to Write Dynamic Configuration command.
