   Demonstration program for:

   Generic 16-bit manual-reload scheduler (using T0).

   Assumes 12 MHz oscillator (-> 01 ms tick interval).

   *** All timing is in TICKS (not milliseconds) ***


   Required linker options (see Chapter 14 for details):

   OVERLAY (main ~ (LED_Flash_Update), 
   SCH_dispatch_tasks ! (LED_Flash_Update))
