Introduction
The Watchdog Timer (WDT) is a free running on-chip RC oscillator which does not require any
external components. The block diagram is shown in
from the device RC oscillator of the OSC1/CLKIN pin. This means that the WDT will run, even if
the clock on the OSC1 and OSC2 pins has been stopped, for example, by execution of a
instruction.
The Watchdog Timer (WDT) is enabled/disabled by a device configuration bit. If the WDT is
enabled, software execution may not disable this function.
