*                                      TICKER INITIALIZATION
*
* Description : This function is used to initialize one of the eight output compares to generate an
*               interrupt at the desired tick rate.  You must decide which output compare you will be
*               using by setting the configuration variable OS_TICK_OC (see OS_CFG.H and also OS_CPU_A.S) 
*               to 0..7 depending on which output compare to use.
*                   OS_TICK_OC set to 0 chooses output compare #0 as the ticker source
*                   OS_TICK_OC set to 1 chooses output compare #1 as the ticker source
*                   OS_TICK_OC set to 2 chooses output compare #2 as the ticker source
*                   OS_TICK_OC set to 3 chooses output compare #3 as the ticker source
*                   OS_TICK_OC set to 4 chooses output compare #4 as the ticker source
*                   OS_TICK_OC set to 5 chooses output compare #5 as the ticker source
*                   OS_TICK_OC set to 6 chooses output compare #6 as the ticker source
*                   OS_TICK_OC set to 7 chooses output compare #7 as the ticker source
* Arguments   : none
* Notes       : 1) It is assumed that you have set the prescaler rate of the free running timer within
*                  the first 64 E clock cycles of the 68HC12.
*               2) CPU registers are define in 6812dp256.h (see Metrowerks codewarrior compiler)
