  * @brief   SMARTCARD HAL module driver.
  *          This file provides extended firmware functions to manage the following
  *          functionalities of the SmartCard.
  *           + Initialization and de-initialization functions
  *           + Peripheral Control functions

  =============================================================================
  [..]
  The Extended SMARTCARD HAL driver can be used as follows:

    (#) After having configured the SMARTCARD basic features with HAL_SMARTCARD_Init(),
        then program SMARTCARD advanced features if required (TX/RX pins swap, TimeOut,
        auto-retry counter,...) in the hsmartcard AdvancedInit structure.

  This subsection provides a set of functions allowing to initialize the SMARTCARD.
     (+) HAL_SMARTCARDEx_BlockLength_Config() API allows to configure the Block Length on the fly
     (+) HAL_SMARTCARDEx_TimeOut_Config() API allows to configure the receiver timeout value on the fly
     (+) HAL_SMARTCARDEx_EnableReceiverTimeOut() API enables the receiver timeout feature
     (+) HAL_SMARTCARDEx_DisableReceiverTimeOut() API disables the receiver timeout feature
