//  MSP430F23x0 Demo - WDT+ Failsafe Clock, DCO SMCLK
//
//  Description; Allow WDT+ in watchdog 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 even though
//  software has attempted to disable WDT+ clock source.
//  ACLK = n/a, MCLK = SMCLK = default DCO ~1.2MHz
//
