     Specify the PLLCR (PLL Control Register) value.   

      Uncomment the appropriate line by removing the leading double slash: // 
      Only one statement should be uncommented.

      The user's application must set the PLLCR Register before calling any
      of the Flash API functions.
 
      Example:  CLKIN is a 30MHz crystal.  
                The user wants to have a 150Mhz CPU clock (SYSCLKOUT = 150MHz).  
                In this case, PLLCR must be set to 10 (0x000A)
                Uncomment the line: #define PLLCR_VALUE 10
                Comment out the remaining lines with a double slash: //
-----------------------------------------------------------------------------*/

// #define PLLCR_VALUE   0x0008     // SYSCLKOUT = (OSCLK*8)/2
// #define PLLCR_VALUE   0x0007     // SYSCLKOUT = (OSCLK*7)/2
// #define PLLCR_VALUE   0x0006     // SYSCLKOUT = (OSCLK*6)/2
// #define PLLCR_VALUE   0x0005     // SYSCLKOUT = (OSCLK*5)/2
// #define PLLCR_VALUE   0x0004     // SYSCLKOUT = (OSCLK*4)/2
// #define PLLCR_VALUE   0x0003     // SYSCLKOUT = (OSCLK*3)/2
// #define PLLCR_VALUE   0x0002     // SYSCLKOUT = (OSCLK*2)/2
// #define PLLCR_VALUE   0x0001     // SYSCLKOUT = (OSCLK*1)/2
