Detailed Description

Defines a driver for the watchdog interface.

This driver manages the hardware watchdog countdown timer. When enabled, the watchdog timer will generate an interrupt when the timer counts down to zero, then will reload the counter. If the counter counts down to zero again, the hardware performs a device reset. The lowest priority "idle" thread restarts the watchdog counter preiodically, and other operations that may keep the system busy call wiced_hal_wdog_restart to extend the watchdog countdown.

NOTE: This is for debugging purposes only. Hence, there is no complementary "Enable Watchdog" function. Please do not use this function in production applications.
