// Assuming 133 MHz SCLK, programming the Watchdog Count to the following
// value should result in a WDOG expiration every ~2 seconds.  Change this
// value as needed to work with your SCLK
#define		TWO_SECOND_WDOG		0x08000000		// Watch Dog Count
#define		WDOG_EXPIRED_BIT	0x8000			// WDOG_CTL Expired Bit (W1C)
#define		DISABLE_WDOG		0x0AD0			// Disables Watchdog Timer
#define		TOGGLE_ALL			0xFFFF			// Toggles All 16 PF Pins
#define		TOGGLE_LOWER		0x00FF			// Toggles Lower 8 PF Pins
