6.13.1 Watchdog Reset Timer
The watchdog timer is a 15-bit counter that is incremented every 24 or 384 clock cycles. It is used to provide the
system supervision in case of software or hardware upset. If the software was not able to refresh the Watchdog Timer
after 786336 or 12581376 clock cycles (65ms or 1s when using 12MHz clock), an internal reset is generated.
