These bits set the divider ratio of watchdog clocks for 25 MHz.
The clock cycles divided by the "setting value + 2" represent the basic watchdog increment.
The default value is 100 μs = 2498.

These bits set the overflow time of PDI watchdog as the number of basic watchdog
increments.
The default value with watchdog divider 100 μs means 100 μs x 1000 = 100 ms watchdog.
The watchdog is disabled if these bits are set to 0. The watchdog is restarted with every PDI
access.
