The watchdog timer supports following features:
- A 32-bit timer counts down from a preset value to zero, then performs one of the following user-configurable operations: If the counter is not refreshed, it times out and either causes a system reset or generates an interrupt to the processor.
- The watchdog timer counter is halted when the processor enters the Debug state.
- The watchdog timer can be configured to generate a wake-up interrupt when the processor is in Sleep mode.
The watchdog timer is connected to the MSS AMBA interconnect through the APB interface.
