These bits set the overflow time of the process data watchdog as the number of basic
watchdog increments.
The default value with watchdog divider 100 μs means 100 μs x 1000 = 100 ms watchdog.
There is one watchdog for all SyncManagers. The watchdog is disabled if these bits are set
to 0. The watchdog is restarted with every write access to SyncManagers with the watchdog
trigger enable bit set.
