main.c

根据freescale XXDZ60的多用途时钟发生器的设置原理

#include <hidef.h> /* for EnableInterrupts macro */
#include "derivative.h" /* include peripheral declarations */




void main(void) {
  unsigned int wCount;
  
  EnableInterrupts; /* enable interrupts */
  /* include your code here */
  PTDDD = 0xFF;
  PTDD = 0x55;


 
  for(;;) 
  {
    for (wCount = 0; wCount < 0xfff0; wCount++) 
    { }      
      if (PTDD == 0x55) 
         {
           PTDD = 0xA6;
         }
      else 
        {
          PTDD = 0x55;
        }
    
    __RESET_WATCHDOG(); /* feeds the dog */
  } /* loop forever */
  /* please make sure that you never leave main */
}
