- * Needs board with 2 available openpic timers
- *
- * 'timer_instdis(timer, install, period)'
- *
- * installs 'timer_isr' to openpic timer # 'timer'.
- * The interrupt priority is set to 8 + timer#
- *
- * The timer_isr prints a message then polls
- * the variable 'timer_poll' while it has the value
- * of the timer # then sets it to -1 and prints
- * the 'leave' message.
- *
- * To test nested interrupts:
- *
- *  timer_instdis(0, 1, period)
- *  wait_a_bit()
- *  timer_instdis(1, 1, period)
- *  timer_poll = 0;
- *
- *  As soon as timer 0's IRQ fires the
- *  isr prints
- *     TIMER ISR (0) ...
- *  then starts polling (since timer_poll == 0 )
- *  eventually, timer 1 goes off, interrupts (because
- *  it's priority is 9 (i.e., higher than timer 0's priority)
- *  and prints
- *     TIMER ISR (1)
- *  it skips polling since timer_poll is 0, not 1 but
- *  resets timer_poll -1 and prints
- *     Leaving ISR (1)
- *  timer 0 isr resumes polling and finds timer_poll == -1
- *  so it also writes -1 to timer_poll and exits, printing
- *     Leaving ISR (0)
- *
- *  The timer IRQs can be unhooked with
- *     timer_instdis( 0, 0, period );
- *     timer_instdis( 1, 0, period );
