| range 4 256 |
| help |
| Set the prescaler divider for the clock feeding the Independent |
| Watchdog. Higher values indicate that the watchdog will need to |
| be reloaded more frequently. Allowed values: 4, 8, 16, 32, 64, |
| 128, 256. This setting combined with reload counter defines the |
| watchdog countdown time. |

| help |
| Configure the value to be loaded into the watchdog's counter each |
| time a reload operation is performed. This value combined with |
| prescaler setting defines the watchdog countdown time. |

| help |
| Enable this setting to allow IWDG to be automatically started |
| during device initialization. Note that once IWDG is started |
| it must be reloaded before the counter reaches 0, otherwise |
| the MCU will be reset. |
