There is an interrupt that isn't being handled:
"main 0 0, main 1 10000000, high int"
where I added "high int" if (selectCause & HI_INT_CAUSE) is set in
It's hard to sort out the interrupt stuff since those registers are in
the document that is only available with a non-disclosure agreement.
This generates an external interrupt continuously, which keeps the
decrementer from counting except occasionally (I guess, I don't know
why it runs at all).
Thus when I run ticker.c I see the ticks that should be five seconds
apart 750 seconds apart.
Maybe you have something handling that interrupt and clearing the
