|
|
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.

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.

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.
