* @brief GPIO Extension HAL module driver. | |
* This file provides firmware functions to manage the following | |
* functionalities of the General Purpose Input/Output (GPIO) extension peripheral. | |
* + Extended features functions | |

============================================================================== | |
##### GPIO Peripheral extension features ##### | |
============================================================================== | |
[..] GPIO module on STM32F1 family, manage also the AFIO register: | |
(+) Possibility to use the EVENTOUT Cortex feature | |
##### How to use this driver ##### | |
============================================================================== | |
[..] This driver provides functions to use EVENTOUT Cortex feature | |
(#) Configure EVENTOUT Cortex feature using the function HAL_GPIOEx_ConfigEventout() | |
(#) Activate EVENTOUT Cortex feature using the HAL_GPIOEx_EnableEventout() | |
(#) Deactivate EVENTOUT Cortex feature using the HAL_GPIOEx_DisableEventout() | |
