mbed_official 125:23cc3068a9e4 15 ==============================================================================
mbed_official 125:23cc3068a9e4 16 ##### WWDG features #####
mbed_official 125:23cc3068a9e4 17 ==============================================================================
mbed_official 125:23cc3068a9e4 18
mbed_official 125:23cc3068a9e4 19 [..] Once enabled the WWDG generates a system reset on expiry of a programmed
mbed_official 125:23cc3068a9e4 20 time period, unless the program refreshes the counter (downcounter)
mbed_official 125:23cc3068a9e4 21 before to reach 0x3F value (i.e. a reset is generated when the counter
mbed_official 125:23cc3068a9e4 22 value rolls over from 0x40 to 0x3F).
mbed_official 125:23cc3068a9e4 23 [..] An MCU reset is also generated if the counter value is refreshed
mbed_official 125:23cc3068a9e4 24 before the counter has reached the refresh window value. This
mbed_official 125:23cc3068a9e4 25 implies that the counter must be refreshed in a limited window.
mbed_official 125:23cc3068a9e4 26
mbed_official 125:23cc3068a9e4 27 [..] Once enabled the WWDG cannot be disabled except by a system reset.
mbed_official 125:23cc3068a9e4 28
mbed_official 125:23cc3068a9e4 29 [..] WWDGRST flag in RCC_CSR register can be used to inform when a WWDG
mbed_official 125:23cc3068a9e4 30 reset occurs.
mbed_official 125:23cc3068a9e4 31
mbed_official 125:23cc3068a9e4 32 [..] The WWDG counter input clock is derived from the APB clock divided
mbed_official 125:23cc3068a9e4 33 by a programmable prescaler.
mbed_official 125:23cc3068a9e4 34
mbed_official 125:23cc3068a9e4 35 [..] WWDG counter clock = PCLK1 / Prescaler.
mbed_official 125:23cc3068a9e4 36 [..] WWDG timeout = (WWDG counter clock) * (counter value).
mbed_official 125:23cc3068a9e4 37
mbed_official 125:23cc3068a9e4 38 [..] Min-max timeout value @36MHz (PCLK1): ~114us / ~58.3ms.
mbed_official 125:23cc3068a9e4 39
mbed_official 125:23cc3068a9e4 40 ##### How to use this driver #####
mbed_official 125:23cc3068a9e4 41 ==============================================================================
mbed_official 125:23cc3068a9e4 42 [..]
mbed_official 125:23cc3068a9e4 43 (#) Enable WWDG clock using RCC_APB1PeriphClockCmd(RCC_APB1Periph_WWDG, ENABLE)
mbed_official 125:23cc3068a9e4 44 function.
mbed_official 125:23cc3068a9e4 45
mbed_official 125:23cc3068a9e4 46 (#) Configure the WWDG prescaler using WWDG_SetPrescaler() function.
mbed_official 125:23cc3068a9e4 47
mbed_official 125:23cc3068a9e4 48 (#) Configure the WWDG refresh window using WWDG_SetWindowValue() function.
mbed_official 125:23cc3068a9e4 49
mbed_official 125:23cc3068a9e4 50 (#) Set the WWDG counter value and start it using WWDG_Enable() function.
mbed_official 125:23cc3068a9e4 51 When the WWDG is enabled the counter value should be configured to
mbed_official 125:23cc3068a9e4 52 a value greater than 0x40 to prevent generating an immediate reset.
mbed_official 125:23cc3068a9e4 53
mbed_official 125:23cc3068a9e4 54 (#) Optionally you can enable the Early wakeup interrupt which is
mbed_official 125:23cc3068a9e4 55 generated when the counter reach 0x40.
mbed_official 125:23cc3068a9e4 56 Once enabled this interrupt cannot be disabled except by a system reset.
mbed_official 125:23cc3068a9e4 57
mbed_official 125:23cc3068a9e4 58 (#) Then the application program must refresh the WWDG counter at regular
mbed_official 125:23cc3068a9e4 59 intervals during normal operation to prevent an MCU reset, using
mbed_official 125:23cc3068a9e4 60 WWDG_SetCounter() function. This operation must occur only when
mbed_official 125:23cc3068a9e4 61 the counter value is lower than the refresh window value,
mbed_official 125:23cc3068a9e4 62 programmed using WWDG_SetWindowValue().
