Defines | |
| #define | IS_IWDG_PRESCALER_OK(VALUE) |
| Macro used by the assert function in order to check the different values of the prescaler. | |
| #define | IS_IWDG_WRITEACCESS_MODE_OK(MODE) (((MODE) == IWDG_WriteAccess_Enable) || ((MODE) == IWDG_WriteAccess_Disable)) |
| Macro used by the assert function in order to check the different values of the counter register. | |
| #define | IWDG_KEY_ENABLE ((uint8_t)0xCC) |
| Define used to start the watchdog counter down. | |
| #define | IWDG_KEY_REFRESH ((uint8_t)0xAA) |
| Define used to prevent watchdog reset. | |
