* MSP430 CODE EXAMPLE DISCLAIMER
*
* MSP430 code examples are self-contained low-level programs that typically
* demonstrate a single peripheral function or device feature in a highly
* concise manner. For this the code may rely on the device's power-on default
* register values and settings such as the clock configuration and care must
* be taken when combining code from several examples to avoid potential side
* effects. Also see www.ti.com/grace for a GUI- and www.ti.com/msp430ware
* for an API functional library-approach to peripheral configuration.

// MSP430G2xx1 Demo - WDT+ Failsafe Clock, DCO SMCLK
//
// Description; Allow WDT+ in watchdog to timeout. Toggle P1.0 in main
// funnction. LPM4 is entered, this example will demonstrate WDT+ feature
// of preventing WDT+ clock to be disabled.
// The WDT+ will not allow active WDT+ clock to be disabled by software, the
// LED continues to Flash because the WDT times out normally even though
// software has attempted to disable WDT+ clock source.
// The MSP430F1xx will stop code execution when software disables WDT+ clock
// source.
// ACLK = n/a, MCLK = SMCLK = default DCO
