Ok, I give up. I've been battling the developers package documentation
long enough, so someone educate me:

I'm trying to get a 5Khz tick value by using Xbtimer(), and a service
routine. I kluged up a program to test this out, and its:

long tick=0;
int kick_count();

main()
{
	Xbtimer(0, 1, 122, &kick_count); /* gives a clock of 5039.xxx Hz */

	/* .. When I want the value of the tick, I just use tick */
}

kick_count() is in assembler which only increments tick. It does not
use any registers at all.

Of course the program doesn't run, and crashes after the call to Xbtimer().

Now the question: How do I get the damn thing to work?  Which return
do I use on my kick_count routine, and rts, rte, or an rtr? And do
I have to hack anything on the stack before the return to get this to work???

Help! I am going nuts!

Could some kind soul send me a code example, both for the call to Xbtimer()
and the little service routine to increment tick???

Thanx in advance,
