sahilmgandhi 18:6a4db94011d3 14 ==============================================================================
sahilmgandhi 18:6a4db94011d3 15 ##### WWDG specific features #####
sahilmgandhi 18:6a4db94011d3 16 ==============================================================================
sahilmgandhi 18:6a4db94011d3 17 [..]
sahilmgandhi 18:6a4db94011d3 18 Once enabled the WWDG generates a system reset on expiry of a programmed
sahilmgandhi 18:6a4db94011d3 19 time period, unless the program refreshes the counter (downcounter)
sahilmgandhi 18:6a4db94011d3 20 before reaching 0x3F value (i.e. a reset is generated when the counter
sahilmgandhi 18:6a4db94011d3 21 value rolls over from 0x40 to 0x3F).
sahilmgandhi 18:6a4db94011d3 22
sahilmgandhi 18:6a4db94011d3 23 (+) An MCU reset is also generated if the counter value is refreshed
sahilmgandhi 18:6a4db94011d3 24 before the counter has reached the refresh window value. This
sahilmgandhi 18:6a4db94011d3 25 implies that the counter must be refreshed in a limited window.
sahilmgandhi 18:6a4db94011d3 26 (+) Once enabled the WWDG cannot be disabled except by a system reset.
sahilmgandhi 18:6a4db94011d3 27 (+) WWDGRST flag in RCC_CSR register can be used to inform when a WWDG
sahilmgandhi 18:6a4db94011d3 28 reset occurs.
sahilmgandhi 18:6a4db94011d3 29 (+) The WWDG counter input clock is derived from the APB clock divided
sahilmgandhi 18:6a4db94011d3 30 by a programmable prescaler.
sahilmgandhi 18:6a4db94011d3 31 (+) WWDG clock (Hz) = PCLK1 / (4096 * Prescaler)
sahilmgandhi 18:6a4db94011d3 32 (+) WWDG timeout (mS) = 1000 * Counter / WWDG clock
sahilmgandhi 18:6a4db94011d3 33 (+) WWDG Counter refresh is allowed between the following limits :
sahilmgandhi 18:6a4db94011d3 34 (++) min time (mS) = 1000 * (Counter _ Window) / WWDG clock
sahilmgandhi 18:6a4db94011d3 35 (++) max time (mS) = 1000 * (Counter _ 0x40) / WWDG clock
sahilmgandhi 18:6a4db94011d3 36
sahilmgandhi 18:6a4db94011d3 37 (+) Min-max timeout value at 50 MHz(PCLK1): 81.9 us / 41.9 ms
sahilmgandhi 18:6a4db94011d3 38
sahilmgandhi 18:6a4db94011d3 39 (+) The Early Wakeup Interrupt (EWI) can be used if specific safety
sahilmgandhi 18:6a4db94011d3 40 operations or data logging must be performed before the actual reset is
sahilmgandhi 18:6a4db94011d3 41 generated. When the downcounter reaches the value 0x40, an EWI interrupt
sahilmgandhi 18:6a4db94011d3 42 is generated and the corresponding interrupt service routine (ISR) can
sahilmgandhi 18:6a4db94011d3 43 be used to trigger specific actions (such as communications or data
sahilmgandhi 18:6a4db94011d3 44 logging), before resetting the device.
sahilmgandhi 18:6a4db94011d3 45 In some applications, the EWI interrupt can be used to manage a software
sahilmgandhi 18:6a4db94011d3 46 system check and/or system recovery/graceful degradation, without
sahilmgandhi 18:6a4db94011d3 47 generating a WWDG reset. In this case, the corresponding interrupt
sahilmgandhi 18:6a4db94011d3 48 service routine (ISR) should reload the WWDG counter to avoid the WWDG
sahilmgandhi 18:6a4db94011d3 49 reset, then trigger the required actions.
sahilmgandhi 18:6a4db94011d3 50 Note:When the EWI interrupt cannot be served, e.g. due to a system lock
sahilmgandhi 18:6a4db94011d3 51 in a higher priority task, the WWDG reset will eventually be generated.
sahilmgandhi 18:6a4db94011d3 52
sahilmgandhi 18:6a4db94011d3 53 (+) Debug mode : When the microcontroller enters debug mode (core halted),
sahilmgandhi 18:6a4db94011d3 54 the WWDG counter either continues to work normally or stops, depending
sahilmgandhi 18:6a4db94011d3 55 on DBG_WWDG_STOP configuration bit in DBG module, accessible through
sahilmgandhi 18:6a4db94011d3 56 __HAL_DBGMCU_FREEZE_WWDG() and __HAL_DBGMCU_UNFREEZE_WWDG() macros
sahilmgandhi 18:6a4db94011d3 57
sahilmgandhi 18:6a4db94011d3 58 ##### How to use this driver #####
sahilmgandhi 18:6a4db94011d3 59 ==============================================================================
sahilmgandhi 18:6a4db94011d3 60 [..]
sahilmgandhi 18:6a4db94011d3 61 (+) Enable WWDG APB1 clock using __HAL_RCC_WWDG_CLK_ENABLE().
sahilmgandhi 18:6a4db94011d3 62
sahilmgandhi 18:6a4db94011d3 63 (+) Set the WWDG prescaler, refresh window, counter value and Early Wakeup
sahilmgandhi 18:6a4db94011d3 64 Interrupt mode using using HAL_WWDG_Init() function.
sahilmgandhi 18:6a4db94011d3 65 This enables WWDG peripheral and the downcounter starts downcounting
sahilmgandhi 18:6a4db94011d3 66 from given counter value.
sahilmgandhi 18:6a4db94011d3 67 Init function can be called again to modify all watchdog parameters,
sahilmgandhi 18:6a4db94011d3 68 however if EWI mode has been set once, it can't be clear until next
sahilmgandhi 18:6a4db94011d3 69 reset.
sahilmgandhi 18:6a4db94011d3 70
sahilmgandhi 18:6a4db94011d3 71 (+) The application program must refresh the WWDG counter at regular
sahilmgandhi 18:6a4db94011d3 72 intervals during normal operation to prevent an MCU reset using
sahilmgandhi 18:6a4db94011d3 73 HAL_WWDG_Refresh() function. This operation must occur only when
sahilmgandhi 18:6a4db94011d3 74 the counter is lower than the window value already programmed.
sahilmgandhi 18:6a4db94011d3 75
sahilmgandhi 18:6a4db94011d3 76 (+) if Early Wakeup Interrupt mode is enable an interrupt is generated when
sahilmgandhi 18:6a4db94011d3 77 the counter reaches 0x40. User can add his own code in weak function
sahilmgandhi 18:6a4db94011d3 78 HAL_WWDG_EarlyWakeupCallback().
