/* WATCHDOG TIMER DEFINITIONS */
// WDCTL bit definitions

#define WDINT0     0x01  // Interval, bit0
#define WDINT1     0x02  // Interval, bit1
#define WDINT      0x03  // Interval, mask
#define WDMODE     0x04  // Mode: watchdog=0, timer=1
#define WDEN       0x08  // Timer: disabled=0, enabled=1
#define WDCLR0     0x10  // Clear timer, bit0
#define WDCLR1     0x20  // Clear timer, bit1
#define WDCLR2     0x40  // Clear timer, bit2
#define WDCLR3     0x80  // Clear timer, bit3
#define WDCLR      0xF0  // Clear timer, mask

// WD timer intervals
#define WDTISH     0x03  // Short: clk * 64
#define WDTIMD     0x02  // Medium: clk * 512
#define WDTILG     0x01  // Long: clk * 8192
#define WDTIMX     0x00  // Maximum: clk * 32768

// WD clear timer patterns
#define WDCLP1     0xA0  // Clear pattern 1
#define WDCLP2     0x50  // Clear pattern 2


/* WATCHDOG TIMER DEFINITIONS */
#define WatchDogEnable(wdti)              \
{                                         \
  WDCTL = WDCLP1 | WDEN | (wdti & WDINT); \
  WDCTL = WDCLP2 | WDEN | (wdti & WDINT); \
}

#define WatchDogFeed()              \
{                                         \
  WDCTL = WDCLP1; \
  WDCTL = WDCLP2; \
}

使用方法;

 // Start watchdog
  WatchDogEnable(WDTIMX);  

然后要喂狗的地方调用

WatchDogFeed()
