For that you need to include the gpio. Port Output Set Register. For that you need to include the gpio. Port Output Clear Register.

Writing to this register places corresponding values in all bits of the particular PORT pins. This register controls the state of output pins.

Writing 0s has no effect. The below sample code shows how to use the GPIO functions.

Reading this register returns the current contents of the port output register, not the physical port value. This register controls the state of output pins. As there can be up to 4 functions associated with a GPIO pin, two bits for each lpf2148 are available to select the function. Writing 1s produces highs at the corresponding port pins. Port Output Clear Register. Writing 0s has no effect. Reading this register returns the current contents of the port output lpc21148, not the physical port value.
