//  1.00| 11 Sep 2003 | L.H. | First release.  Seperated example specific headers
//      |             |      |     from the DSP28 peripheral headers.
//      |             |      | Added DSP28_BIOS and DSP28_NONBIOS switches
//      |             |      |     to include or not include the default ISR's

      Specify the clock rate of the CPU (SYSCLKOUT) in nS.

      Take into account the input clock frequency and the PLL multiplier
      selected in step 1.
 
      Use one of the values provided, or define your own.
      The trailing L is required tells the compiler to treat 
      the number as a 64-bit value.  

      Only one statement should be uncommented.

      Example:  CLKIN is a 30MHz crystal. 
 
                In step 1 the user specified PLLCR = 0xA for a 
                150Mhz CPU clock (SYSCLKOUT = 150MHz).  

                In this case, the CPU_RATE will be 6.667L
