mbed_official 87:085cde657901 15 ==============================================================================
mbed_official 87:085cde657901 16 ##### IWDG Generic features #####
mbed_official 87:085cde657901 17 ==============================================================================
mbed_official 87:085cde657901 18 [..]
mbed_official 87:085cde657901 19 (+) The IWDG can be started by either software or hardware (configurable
mbed_official 87:085cde657901 20 through option byte).
mbed_official 87:085cde657901 21
mbed_official 87:085cde657901 22 (+) The IWDG is clocked by its own dedicated Low-Speed clock (LSI) and
mbed_official 87:085cde657901 23 thus stays active even if the main clock fails.
mbed_official 87:085cde657901 24 Once the IWDG is started, the LSI is forced ON and cannot be disabled
mbed_official 87:085cde657901 25 (LSI cannot be disabled too), and the counter starts counting down from
mbed_official 87:085cde657901 26 the reset value of 0xFFF. When it reaches the end of count value (0x000)
mbed_official 87:085cde657901 27 a system reset is generated.
mbed_official 87:085cde657901 28
mbed_official 87:085cde657901 29 (+) The IWDG counter should be refreshed at regular intervals, otherwise the
mbed_official 87:085cde657901 30 watchdog generates an MCU reset when the counter reaches 0.
mbed_official 87:085cde657901 31
mbed_official 87:085cde657901 32 (+) The IWDG is implemented in the VDD voltage domain that is still functional
mbed_official 87:085cde657901 33 in STOP and STANDBY mode (IWDG reset can wake-up from STANDBY).
mbed_official 87:085cde657901 34 IWDGRST flag in RCC_CSR register can be used to inform when an IWDG
mbed_official 87:085cde657901 35 reset occurs.
mbed_official 87:085cde657901 36
mbed_official 87:085cde657901 37 (+) Min-max timeout value @32KHz (LSI): ~125us / ~32.7s
mbed_official 87:085cde657901 38 The IWDG timeout may vary due to LSI frequency dispersion. STM32F4xx
mbed_official 87:085cde657901 39 devices provide the capability to measure the LSI frequency (LSI clock
mbed_official 87:085cde657901 40 connected internally to TIM5 CH4 input capture). The measured value
mbed_official 87:085cde657901 41 can be used to have an IWDG timeout with an acceptable accuracy.
mbed_official 87:085cde657901 42
mbed_official 87:085cde657901 43
mbed_official 87:085cde657901 44 ##### How to use this driver #####
mbed_official 87:085cde657901 45 ==============================================================================
mbed_official 87:085cde657901 46 [..]
mbed_official 87:085cde657901 47 (+) Use IWDG using HAL_IWDG_Start() function to:
mbed_official 87:085cde657901 48 (++) Enable write access to IWDG_PR and IWDG_RLR registers.
mbed_official 87:085cde657901 49 (++) Configure the IWDG prescaler and counter reload values.
mbed_official 87:085cde657901 50 (++) Reload IWDG counter with value defined in the IWDG_RLR register.
mbed_official 87:085cde657901 51 (++) Start the IWDG, when the IWDG is used in software mode (no need
mbed_official 87:085cde657901 52 to enable the LSI, it will be enabled by hardware).
mbed_official 87:085cde657901 53 (+) Then the application program must refresh the IWDG counter at regular
mbed_official 87:085cde657901 54 intervals during normal operation to prevent an MCU reset, using
mbed_official 87:085cde657901 55 HAL_IWDG_Refresh() function.
mbed_official 87:085cde657901 56
mbed_official 87:085cde657901 57 *** IWDG HAL driver macros list ***
mbed_official 87:085cde657901 58 ====================================
mbed_official 87:085cde657901 59 [..]
mbed_official 87:085cde657901 60 Below the list of most used macros in IWDG HAL driver.
mbed_official 87:085cde657901 61
mbed_official 87:085cde657901 62 (+) __HAL_IWDG_START: Enable the IWDG peripheral
mbed_official 87:085cde657901 63 (+) __HAL_IWDG_RELOAD_COUNTER: Reloads IWDG counter with value defined in the reload register
mbed_official 87:085cde657901 64 (+) __HAL_IWDG_ENABLE_WRITE_ACCESS : Enable write access to IWDG_PR and IWDG_RLR registers
mbed_official 87:085cde657901 65 (+) __HAL_IWDG_DISABLE_WRITE_ACCESS : Disable write access to IWDG_PR and IWDG_RLR registers
mbed_official 87:085cde657901 66 (+) __HAL_IWDG_GET_FLAG: Get the selected IWDG's flag status
mbed_official 87:085cde657901 67 (+) __HAL_IWDG_CLEAR_FLAG: Clear the IWDG's pending flags
