void WWDG_EnableIT |
( |
void |
| ) |
|

void WWDG_SetCounter |
( |
uint8_t |
Counter | ) |
|
Sets the WWDG counter value.
- Parameters
-
Counter | specifies the watchdog counter value. This parameter must be a number between 0x40 and 0x7F (to prevent generating an immediate reset) |
- Return values

void WWDG_SetPrescaler |
( |
uint32_t |
WWDG_Prescaler | ) |
|
Sets the WWDG Prescaler.
- Parameters
-
WWDG_Prescaler | specifies the WWDG Prescaler. This parameter can be one of the following values:
