Watchdog Timer (WDT)
allows a selectable time-out interval to detect malfunc-
tions. The timer must be reset by software periodically.
Otherwise, a time-out occurs, interrupting the system.
If the interrupt is not serviced within the timeout period,
the WDT triggers the RCPC to generate a System
Reset. If the WDT times out, it sets a bit in the RCPC
Reset Status Register.
a time-out of 216 through 231 system clock cycles. All
Control and Status Registers for the Watchdog Timer
are accessed through the APB.
