IO Port speed does not match BUSCLK frequency

KL25, external oscillator 8Mhz, core freq. 48Mhz, bus freq. 24Mhz.

when I test the bus speed with the following code, the max freq. speed is 8 Mhz and not 24Mhz, why?

How do I must configure the microprocessor?

 

  while (1)

  {

  GPIOB_PCOR = 0x00000100;

  GPIOB_PSOR = 0x00000100;

  GPIOB_PCOR = 0x00000100;

  GPIOB_PSOR = 0x00000100;

  GPIOB_PCOR = 0x00000100;

  GPIOB_PSOR = 0x00000100;

  GPIOB_PCOR = 0x00000100;

  GPIOB_PSOR = 0x00000100;

  GPIOB_PCOR = 0x00000100;

  GPIOB_PSOR = 0x00000100;

}

 

Thanks
