Function
Watchdog timer status flag. Set when the watchdog timer was started. Can be
read by software.

Prescaler select bit. When set, the watchdog is clocked through an additional
divide-by-16 prescaler
Seven bit reload value for the high-byte of the watchdog timer. This value is
loaded to the WDT when a refresh is triggered by a consecutive setting of bits
WDT and SWDT.
