//  MSP430x26x 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
