* @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
@verbatim
===============================================================================
##### How to use this driver #####
===============================================================================
[..]
The Extended SMARTCARD HAL driver can be used as follow:
(#) After having configured the SMARTCARD basic features with HAL_SMARTCARD_Init(),
then if required, program SMARTCARD advanced features (TX/RX pins swap, TimeOut,
auto-retry counter,...) in the hsc 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
