MPC8313e GPIOs

  I am trying to use the MPC8313e GPIOs . I toggle them from CodeWarrior. I have verified that the way of accessing the registers is the right one and I have been able to change the registers of other peripherals.

On the other hand I always read '0 ' from the GPIO data register even some GPIOs having pull-up. I configure them as output and try to toggle them writing in its respective register  but do not toggle, I check this by hardware (scope) and by software.

Does anyone have any idea?
