| * @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 | |

| =============================================================================== | |
| ##### 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. | |
