How time is 3 second?
WDT - Failsafe Clock, 10KHz VLOCLK
//!
//! Configure WDT in watchdog to timeout sourced by ACLK. LPM3 is entered. This
//! example will demonstrate WDT fail-safe feature by automatically selecting
//! VLOCLK as WDT clock source if ACLK fails. Watchdog timeout will toggle on
//! P1.0 every 3 seconds in main function.
//! VLOCLK = 10KHZ, ACLK = 32768, MCLK = SMCLK = default DCO ~1.045MHz
//!
//! Tested On: MSP430F5529,MSP430FR5739
