NYX 0:85b3fd62ea1a 8 * This file provides firmware functions to manage the following
NYX 0:85b3fd62ea1a 9 * functionalities of the Window Watchdog (WWDG) peripheral:
NYX 0:85b3fd62ea1a 10 * + Initialization and de-initialization functions

NYX 0:85b3fd62ea1a 14 ==============================================================================
NYX 0:85b3fd62ea1a 15 ##### WWDG specific features #####
NYX 0:85b3fd62ea1a 16 ==============================================================================
NYX 0:85b3fd62ea1a 17 [..]
NYX 0:85b3fd62ea1a 18 Once enabled the WWDG generates a system reset on expiry of a programmed
NYX 0:85b3fd62ea1a 19 time period, unless the program refreshes the counter (downcounter)
NYX 0:85b3fd62ea1a 20 before reaching 0x3F value (i.e. a reset is generated when the counter
NYX 0:85b3fd62ea1a 21 value rolls over from 0x40 to 0x3F).
NYX 0:85b3fd62ea1a 22
NYX 0:85b3fd62ea1a 23 (+) An MCU reset is also generated if the counter value is refreshed
NYX 0:85b3fd62ea1a 24 before the counter has reached the refresh window value. This
NYX 0:85b3fd62ea1a 25 implies that the counter must be refreshed in a limited window.
NYX 0:85b3fd62ea1a 26 (+) Once enabled the WWDG cannot be disabled except by a system reset.
NYX 0:85b3fd62ea1a 27 (+) WWDGRST flag in RCC_CSR register can be used to inform when a WWDG
NYX 0:85b3fd62ea1a 28 reset occurs.
NYX 0:85b3fd62ea1a 29 (+) The WWDG counter input clock is derived from the APB clock divided
NYX 0:85b3fd62ea1a 30 by a programmable prescaler.
NYX 0:85b3fd62ea1a 31 (+) WWDG clock (Hz) = PCLK1 / (4096 * Prescaler)
NYX 0:85b3fd62ea1a 32 (+) WWDG timeout (mS) = 1000 * Counter / WWDG clock
NYX 0:85b3fd62ea1a 33 (+) WWDG Counter refresh is allowed between the following limits :
NYX 0:85b3fd62ea1a 34 (++) min time (mS) = 1000 * (Counter _ Window) / WWDG clock
NYX 0:85b3fd62ea1a 35 (++) max time (mS) = 1000 * (Counter _ 0x40) / WWDG clock
NYX 0:85b3fd62ea1a 36
NYX 0:85b3fd62ea1a 37 (+) Min-max timeout value at 50 MHz(PCLK1): 81.9 us / 41.9 ms
NYX 0:85b3fd62ea1a 38
NYX 0:85b3fd62ea1a 39 (+) The Early Wakeup Interrupt (EWI) can be used if specific safety
NYX 0:85b3fd62ea1a 40 operations or data logging must be performed before the actual reset is
NYX 0:85b3fd62ea1a 41 generated. When the downcounter reaches the value 0x40, an EWI interrupt
NYX 0:85b3fd62ea1a 42 is generated and the corresponding interrupt service routine (ISR) can
NYX 0:85b3fd62ea1a 43 be used to trigger specific actions (such as communications or data
NYX 0:85b3fd62ea1a 44 logging), before resetting the device.
NYX 0:85b3fd62ea1a 45 In some applications, the EWI interrupt can be used to manage a software
NYX 0:85b3fd62ea1a 46 system check and/or system recovery/graceful degradation, without
NYX 0:85b3fd62ea1a 47 generating a WWDG reset. In this case, the corresponding interrupt
NYX 0:85b3fd62ea1a 48 service routine (ISR) should reload the WWDG counter to avoid the WWDG
NYX 0:85b3fd62ea1a 49 reset, then trigger the required actions.
NYX 0:85b3fd62ea1a 50 Note:When the EWI interrupt cannot be served, e.g. due to a system lock
NYX 0:85b3fd62ea1a 51 in a higher priority task, the WWDG reset will eventually be generated.
NYX 0:85b3fd62ea1a 52
NYX 0:85b3fd62ea1a 53 (+) Debug mode : When the microcontroller enters debug mode (core halted),
NYX 0:85b3fd62ea1a 54 the WWDG counter either continues to work normally or stops, depending
NYX 0:85b3fd62ea1a 55 on DBG_WWDG_STOP configuration bit in DBG module, accessible through
NYX 0:85b3fd62ea1a 56 __HAL_DBGMCU_FREEZE_WWDG() and __HAL_DBGMCU_UNFREEZE_WWDG() macros
NYX 0:85b3fd62ea1a 57
NYX 0:85b3fd62ea1a 58 ##### How to use this driver #####
NYX 0:85b3fd62ea1a 59 ==============================================================================
NYX 0:85b3fd62ea1a 60 [..]
NYX 0:85b3fd62ea1a 61 (+) Enable WWDG APB1 clock using __HAL_RCC_WWDG_CLK_ENABLE().
NYX 0:85b3fd62ea1a 62
NYX 0:85b3fd62ea1a 63 (+) Set the WWDG prescaler, refresh window, counter value and Early Wakeup
NYX 0:85b3fd62ea1a 64 Interrupt mode using using HAL_WWDG_Init() function.
NYX 0:85b3fd62ea1a 65 This enables WWDG peripheral and the downcounter starts downcounting
NYX 0:85b3fd62ea1a 66 from given counter value.
NYX 0:85b3fd62ea1a 67 Init function can be called again to modify all watchdog parameters,
NYX 0:85b3fd62ea1a 68 however if EWI mode has been set once, it can't be clear until next
NYX 0:85b3fd62ea1a 69 reset.
NYX 0:85b3fd62ea1a 70
NYX 0:85b3fd62ea1a 71 (+) The application program must refresh the WWDG counter at regular
NYX 0:85b3fd62ea1a 72 intervals during normal operation to prevent an MCU reset using
NYX 0:85b3fd62ea1a 73 HAL_WWDG_Refresh() function. This operation must occur only when
NYX 0:85b3fd62ea1a 74 the counter is lower than the window value already programmed.
NYX 0:85b3fd62ea1a 75
NYX 0:85b3fd62ea1a 76 (+) if Early Wakeup Interrupt mode is enable an interrupt is generated when
NYX 0:85b3fd62ea1a 77 the counter reaches 0x40. User can add his own code in weak function
NYX 0:85b3fd62ea1a 78 HAL_WWDG_EarlyWakeupCallback().
NYX 0:85b3fd62ea1a 79
NYX 0:85b3fd62ea1a 80 *** WWDG HAL driver macros list ***
NYX 0:85b3fd62ea1a 81 ==================================
NYX 0:85b3fd62ea1a 82 [..]
NYX 0:85b3fd62ea1a 83 Below the list of most used macros in WWDG HAL driver.
NYX 0:85b3fd62ea1a 84
NYX 0:85b3fd62ea1a 85 (+) __HAL_WWDG_GET_IT_SOURCE: Check the selected WWDG's interrupt source.
NYX 0:85b3fd62ea1a 86 (+) __HAL_WWDG_GET_FLAG: Get the selected WWDG's flag status.
NYX 0:85b3fd62ea1a 87 (+) __HAL_WWDG_CLEAR_FLAG: Clear the WWDG's pending flags.
