Timer 2 Example Program
=======================

This example program shows how to configure timer/counter 2 on the
Infineon 80C517 as a 16-bit timer.  An interrupt service routine (ISR)
is invoked each time the timer overflows.  Inside the ISR, a variable
called overflow_count is incremented by one.

To test this program...

1. Start the debugger.
2. Set a breakpoint on the 'overflow_count++' line in the ISR.
3. Run the program.

Each time the interrupt routine is invoked, the debugger will stop
running the program.  Position the cursor over 'overflow_count' to
see its current value.
