Description
Watchdog pre-scaler. In normal mode, the 16-bit watchdog timer is clocked by the
input clock (32.768kHz). The PRE bits set which of the upper bits of the counter are
used as the watchdog output following:
[3:0]
0000
0001
0010
0011
0100

1010 to 1111
Watchdog interrupt response bit.
When clear, watchdog will generate a system reset when the watchdog time out
period has expired
When set, the watchdog will generate a interrupt when the watchdog time out
period has expired.
