// TITLE: Servicing Watchdog Example
|

//
|
||||
//! \addtogroup driver_example_list
|
||||
//! <h1> Watchdog </h1>
|
||||
//!
|
||||
//! This example shows how to service the watchdog or generate a wakeup
|
||||
//! interrupt using the watchdog. By default the example will generate a
|
||||
//! Wake interrupt. To service the watchdog and not generate the interrupt,
|
||||
//! uncomment the SysCtl_serviceWatchdog() line in the main for loop.
|
||||
//!
|
||||
//! \b External \b Connections \n
|
||||
//! - None.
|
||||
//!
|
||||
//! \b Watch \b Variables \n
|
||||
//! - wakeCount - The number of times entered into the watchdog ISR
|
||||
//! - loopCount - The number of loops performed while not in ISR
|
||||
//!
