| 5 | * @brief SMARTCARD HAL module driver. | |
| 6 | * This file provides extended firmware functions to manage the following | |
| 7 | * functionalities of the SmartCard. | |
| 8 | * + Initialization and de-initialization functions | |
| 9 | * + Peripheral Control functions | |

| 16 | [..] | |
| 17 | The Extended SMARTCARD HAL driver can be used as follows: | |
| 18 | ||
| 19 | (#) After having configured the SMARTCARD basic features with HAL_SMARTCARD_Init(), | |
| 20 | then program SMARTCARD advanced features if required (TX/RX pins swap, TimeOut, | |
| 21 | auto-retry counter,...) in the hsmartcard AdvancedInit structure. | |
