| * @brief SD card Extended HAL module driver. |
| * This file provides firmware functions to manage the following |
| * functionalities of the Secure Digital (SD) peripheral: |
| * + Extended features functions |
| * |
| @verbatim |
| ============================================================================== |
| ##### How to use this driver ##### |
| ============================================================================== |
| [..] |
| The SD Extension HAL driver can be used as follows: |
| (+) Set card in High Speed mode using HAL_SDEx_HighSpeed() function. |
| (+) Configure Buffer0 and Buffer1 start address and Buffer size using HAL_SDEx_ConfigDMAMultiBuffer() function. |
| (+) Start Read and Write for multibuffer mode using HAL_SDEx_ReadBlocksDMAMultiBuffer() and HAL_SDEx_WriteBlocksDMAMultiBuffer() functions. |
