2.4.3 Watchdog
The ST92F120/F124/F150/F250 watchdog can be enabled either by hardware or by software.
Pin HW0SW1 is used to define the selection mode. If pin HW0SW1 is connected to the
ground, the watchdog is selected by hardware. If pin HW0SF1 is connected to the Vcc, the
watchdog is selected by software if the application needs it.
