Macros
#define	XTIMER_MIN_SPIN   _xtimer_usec_from_ticks(1)
	Minimal value xtimer_spin() can spin.
#define	MSG_XTIMER   12345
	IPC message type for xtimer msg callback.
volatile uint64_t	_xtimer_current_time
static uint32_t	_xtimer_lltimer_now (void)
	returns the (masked) low-level timer counter value.
static uint32_t	_xtimer_lltimer_mask (uint32_t val)
	drop bits of a value that don't fit into the low-level timer.
uint32_t	_xtimer_now (void)
	xtimer internal stuff
