This - implies that the counter must be refreshed in a limited window. - (+) Once enabled the WWDG cannot be disabled except by a system reset. - (+) WWDGRST flag in RCC CSR register can be used to inform when a WWDG - reset occurs. - (+) The WWDG counter input clock is derived from the APB clock divided - by a programmable prescaler. - (+) WWDG clock (Hz) = PCLK1 / (4096 * Prescaler) - (+) WWDG timeout (mS) = 1000 * (T[5;0] + 1) / WWDG clock (Hz) - where T[5;0] are the lowest 6 bits of Counter. - (+) WWDG Counter refresh is allowed between the following limits : - (++) min time (mS) = 1000 * (Counter - Window) / WWDG clock - (++) max time (mS) = 1000 * (Counter - 0x40) / WWDG clock - (+) Typical values: - (++) Counter min (T[5;0] = 0x00) @56MHz (PCLK1) with zero prescaler: - max timeout before reset: approximately 73.14µs - (++) Counter max (T[5;0] = 0x3F) @56MHz (PCLK1) with prescaler dividing by 8: - max timeout before reset: approximately 599.18ms - - ============================================================================== - ##### How to use this driver ##### - ============================================================================== - - *** Common driver usage *** - =========================== - - [..] - (+) Enable WWDG APB1 clock using __HAL_RCC_WWDG_CLK_ENABLE(). - (+) Set the WWDG prescaler, refresh window and counter value - using HAL_WWDG_Init() function. - (+) Start the WWDG using HAL_WWDG_Start() function. - When the WWDG is enabled the counter value should be configured to - a value greater than 0x40 to prevent generating an immediate reset. - (+) Optionally you can enable the Early Wakeup Interrupt (EWI) which is - generated when the counter reaches 0x40, and then start the WWDG using - HAL_WWDG_Start_IT(). At EWI HAL_WWDG_WakeupCallback is executed and user can - add his own code by customization of callback HAL_WWDG_WakeupCallback. - Once enabled, EWI interrupt cannot be disabled except by a system reset. - (+) Then the application program must refresh the WWDG counter at regular - intervals during normal operation to prevent an MCU reset, using - HAL_WWDG_Refresh() function. This operation must occur only when - the counter is lower than the refresh window value already programmed. - - *** Callback registration *** - ============================= - - [..] - The compilation define USE_HAL_WWDG_REGISTER_CALLBACKS when set to 1 allows - the user to configure dynamically the driver callbacks. Use Functions - @ref HAL_WWDG_RegisterCallback() to register a user callback. - - (+) Function @ref HAL_WWDG_RegisterCallback() allows to register following - callbacks: - (++) EwiCallback : callback for Early WakeUp Interrupt. - (++) MspInitCallback : WWDG MspInit. - This function takes as parameters the HAL peripheral handle, the Callback ID - and a pointer to the user callback function. - - (+) Use function @ref HAL_WWDG_UnRegisterCallback() to reset a callback to - the default weak (surcharged) function. @ref HAL_WWDG_UnRegisterCallback() - takes as parameters the HAL peripheral handle and the Callback ID. - This function allows to reset following callbacks: - (++) EwiCallback : callback for Early WakeUp Interrupt. - (++) MspInitCallback : WWDG MspInit. - - [..] - When calling @ref HAL_WWDG_Init function, callbacks are reset to the - corresponding legacy weak (surcharged) functions: - @ref HAL_WWDG_EarlyWakeupCallback() and HAL_WWDG_MspInit() only if they have - not been registered before. - - [..] - When compilation define USE_HAL_WWDG_REGISTER_CALLBACKS is set to 0 or - not defined, the callback registering feature is not available - and weak (surcharged) callbacks are used. - - *** WWDG HAL driver macros list *** - =================================== - [..] - Below the list of most used macros in WWDG HAL driver. - (+) __HAL_WWDG_ENABLE: Enable the WWDG peripheral - (+) __HAL_WWDG_GET_FLAG: Get the selected WWDG's flag status - (+) __HAL_WWDG_CLEAR_FLAG: Clear the WWDG's pending flags - (+) __HAL_WWDG_ENABLE_IT: Enable the WWDG early wakeup interrupt - - @endverbatim - ****************************************************************************** - * @attention - * - *
