SetTimerAlarm()

s32 SetTimerAlarm	(	u64	clock_cycles,
		timer_alarm_handler_t	callback_handler,
		void *	arg )

Sets up alarm paramenters.

Parameters

clock_cycles	Number of bus cycles when the alarm will trigger
callback_handler	Function pointer to call when the alarm triggers (in IRQ)
arg	Argument to pass to callback_handler

Starts the alarm. If the alarm was already started, it does nothing.
