Prescaler bit. When set, the watchdog is clocked through an
additional divide-by-64 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.
Watchdog timer reset flag. If bit WDTS is ‘1’ after reset, the
reset has been initiated by the watchdog timer. After external
reset, WDTS is reset to ‘0’.
Watchdog timer start flag. Set to activate the watchdog timer.
When directly set after setting WDT, a watchdog timer refresh
is performed.
