<> 144:ef7eb2e8f9f7 15 ##### WWDG specific features #####

<> 144:ef7eb2e8f9f7 17 [..]
<> 144:ef7eb2e8f9f7 18 Once enabled the WWDG generates a system reset on expiry of a programmed
<> 144:ef7eb2e8f9f7 19 time period, unless the program refreshes the counter (downcounter)
<> 144:ef7eb2e8f9f7 20 before reaching 0x3F value (i.e. a reset is generated when the counter
<> 144:ef7eb2e8f9f7 21 value rolls over from 0x40 to 0x3F).
<> 144:ef7eb2e8f9f7 22
<> 144:ef7eb2e8f9f7 23 (+) An MCU reset is also generated if the counter value is refreshed
<> 144:ef7eb2e8f9f7 24 before the counter has reached the refresh window value. This
<> 144:ef7eb2e8f9f7 25 implies that the counter must be refreshed in a limited window.
<> 144:ef7eb2e8f9f7 26 (+) Once enabled the WWDG cannot be disabled except by a system reset.
<> 144:ef7eb2e8f9f7 27 (+) WWDGRST flag in RCC_CSR register can be used to inform when a WWDG
<> 144:ef7eb2e8f9f7 28 reset occurs.
<> 144:ef7eb2e8f9f7 29 (+) The WWDG counter input clock is derived from the APB clock divided
<> 144:ef7eb2e8f9f7 30 by a programmable prescaler.
<> 144:ef7eb2e8f9f7 31 (+) WWDG clock (Hz) = PCLK1 / (4096 * Prescaler)
<> 144:ef7eb2e8f9f7 32 (+) WWDG timeout (mS) = 1000 * Counter / WWDG clock
<> 144:ef7eb2e8f9f7 33 (+) WWDG Counter refresh is allowed between the following limits :
<> 144:ef7eb2e8f9f7 34 (++) min time (mS) = 1000 * (Counter _ Window) / WWDG clock
<> 144:ef7eb2e8f9f7 35 (++) max time (mS) = 1000 * (Counter _ 0x40) / WWDG clock
<> 144:ef7eb2e8f9f7 36
<> 144:ef7eb2e8f9f7 37 (+) Min-max timeout value at 50 MHz(PCLK1): 81.9 us / 41.9 ms
<> 144:ef7eb2e8f9f7 38
<> 144:ef7eb2e8f9f7 39 (+) The Early Wakeup Interrupt (EWI) can be used if specific safety
<> 144:ef7eb2e8f9f7 40 operations or data logging must be performed before the actual reset is
<> 144:ef7eb2e8f9f7 41 generated. When the downcounter reaches the value 0x40, an EWI interrupt
<> 144:ef7eb2e8f9f7 42 is generated and the corresponding interrupt service routine (ISR) can
<> 144:ef7eb2e8f9f7 43 be used to trigger specific actions (such as communications or data
<> 144:ef7eb2e8f9f7 44 logging), before resetting the device.
<> 144:ef7eb2e8f9f7 45 In some applications, the EWI interrupt can be used to manage a software
<> 144:ef7eb2e8f9f7 46 system check and/or system recovery/graceful degradation, without
<> 144:ef7eb2e8f9f7 47 generating a WWDG reset. In this case, the corresponding interrupt
<> 144:ef7eb2e8f9f7 48 service routine (ISR) should reload the WWDG counter to avoid the WWDG
<> 144:ef7eb2e8f9f7 49 reset, then trigger the required actions.
<> 144:ef7eb2e8f9f7 50 Note:When the EWI interrupt cannot be served, e.g. due to a system lock
<> 144:ef7eb2e8f9f7 51 in a higher priority task, the WWDG reset will eventually be generated.
<> 144:ef7eb2e8f9f7 52
<> 144:ef7eb2e8f9f7 53 (+) Debug mode : When the microcontroller enters debug mode (core halted),
<> 144:ef7eb2e8f9f7 54 the WWDG counter either continues to work normally or stops, depending
<> 144:ef7eb2e8f9f7 55 on DBG_WWDG_STOP configuration bit in DBG module, accessible through
<> 144:ef7eb2e8f9f7 56 __HAL_DBGMCU_FREEZE_WWDG() and __HAL_DBGMCU_UNFREEZE_WWDG() macros
<> 144:ef7eb2e8f9f7 57

<> 144:ef7eb2e8f9f7 59 ==============================================================================
<> 144:ef7eb2e8f9f7 60 [..]
<> 144:ef7eb2e8f9f7 61 (+) Enable WWDG APB1 clock using __HAL_RCC_WWDG_CLK_ENABLE().
<> 144:ef7eb2e8f9f7 62
<> 144:ef7eb2e8f9f7 63 (+) Set the WWDG prescaler, refresh window, counter value and Early Wakeup
<> 144:ef7eb2e8f9f7 64 Interrupt mode using using HAL_WWDG_Init() function.
<> 144:ef7eb2e8f9f7 65 This enables WWDG peripheral and the downcounter starts downcounting
<> 144:ef7eb2e8f9f7 66 from given counter value.
<> 144:ef7eb2e8f9f7 67 Init function can be called again to modify all watchdog parameters,
<> 144:ef7eb2e8f9f7 68 however if EWI mode has been set once, it can't be clear until next
<> 144:ef7eb2e8f9f7 69 reset.
<> 144:ef7eb2e8f9f7 70
<> 144:ef7eb2e8f9f7 71 (+) The application program must refresh the WWDG counter at regular
<> 144:ef7eb2e8f9f7 72 intervals during normal operation to prevent an MCU reset using
<> 144:ef7eb2e8f9f7 73 HAL_WWDG_Refresh() function. This operation must occur only when
<> 144:ef7eb2e8f9f7 74 the counter is lower than the window value already programmed.
<> 144:ef7eb2e8f9f7 75
<> 144:ef7eb2e8f9f7 76 (+) if Early Wakeup Interrupt mode is enable an interrupt is generated when
<> 144:ef7eb2e8f9f7 77 the counter reaches 0x40. User can add his own code in weak function
