// MSP430x24x Demo - WDT+ Failsafe Clock, WDT mode, DCO SMCLK
//
// Description; Allow WDT+ in watchdog mode to timeout. Toggle P1.0 in main
// function. 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 (in 32768 DCOCLK
// cycles) even though software has attempted to disable WDT+ clock source.
// ACLK = n/a, MCLK = SMCLK = default DCO ~1.045Mhz
