Hello,

I wrote this little test to see how fast I could toggle an IO pin. 
Using the way I did it here from rising edge to falling edge the time
is only ~540nS.  This seems slow to me.  Is it?  I have verified that
the DesiredSpeed is indeed locked at ~60MHz

Thanks,
Oc.


int main( void)
{ 
  IO1DIR |= (1 << 25); 

  (void)SetNativeSpeed(14746uL);	
  (void)SetDesiredSpeed(60000uL);	

  (void)SetMAM( 3u, MAM_full_enable);
  (void)VPBControl(VPB_DIV1);		
    
 
  
 for(;;)
 {    
   IO1CLR &= ~(1 << 25);
   IO1SET |= (1 << 25);
     
   IO1CLR |=  (1 << 25);
   IO1SET &= ~(1 << 25);	
 }
