Watchdog Timer (WDT)
The WDT consists of a 32-bit down-counter that
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.
The WDT supports 16 selectable time intervals, for
a time-out of 216 through 231 system clock cycles. All
Control and Status Registers for the Watchdog Timer
are accessed through the APB.
WDT FEATURES
Counter generates an interrupt at a set interval and
the count reloads from the pre-set value after reach-
ing zero.
Default timeout period is set to the minimum timeout
of 216 system clock cycles.
WDT is driven by the APB.
Built-in protection mechanism guards against
interrupt-service failure.
WDT can be programmed to trigger a System Reset
on a timeout.
WDT can be programmed to trigger an interrupt on
the first timeout; then, if the service routine fails to
clear the interrupt, the next WDT timeout triggers a
System Reset.
