//
// TITLE: Windowed watchdog expiry with NMI handling
//
//! \addtogroup driver_example_cm_list
//! <h1>Windowed watchdog expiry with NMI handling</h1>
//!
//! This program demonstrates an NMI generation to the CM4 core when
//! the Windowed watchdog ( WWD ) expires.
//!
//! A delay is provided after enabling the WWD to make the watchdog
//! count up from 0 to 0xFF. Once 0 is reached, an NMI is triggered.
//! Currently on triggering an NMI, a status flag is set indicating if the NMI
//! was handled after the WWD expired.
//!
//! \b External \b Connections \n
//! - None
//!
//! \b Watch \b Variables \n
//! - \b wdstatus - Indicates if the WWD caused an NMI on expiry.
//! - \b cmnmi - Indicates if the NMI was handled after the WWD expired
//! - \b fail - Status if the Windowed watchdog expired generating an NMI
//! with proper NMI handling
//!
