* @brief This module implements the functions to drive the ST25DV NFC dynamic tag.
* @details As recommended by the STM32 Cube methodology, this driver provides a standard structure to expose the NFC tag standard API.\n
* It also provides an extended API through its extended driver structure.\n
* To be usable on any MCU, this driver calls several IOBus functions.
* The IOBus functions are implemented outside this driver, and are in charge of accessing the MCU peripherals used for the communication with the tag.
