presented in this appendix.

typedef enum { EONCE_SECOND, EONCE_MILLISECOND, EONCE_MICROSECOND } tunit;

#define READ_IOREG(reg,val) val = *((volatile long *)reg)

#define WRITE_IOREG(reg,val) *((volatile long *)reg) = val

#define MAX_32_BIT 0xffffffff

void EOnCE_stopwatch_timer_init();

void EOnCE_stopwatch_timer_start();

void EOnCE_stopwatch_timer_stop(unsigned long *clock_ext, unsigned long *clock_val);

void EOnCE_LED_init();

void EOnCE_LED_off();

unsigned long Convert_clock2time(unsigned long clock_ext, unsigned long clock_val, short option);
