  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
