Hi

We have assigned SCT output COUT available in PINASSIGN6 to GPIO 13.

    LPC_SWM->PINASSIGN6 = (LPC_SWM->PINASSIGN6 & ~(0xFF<<24)) | ((0*32+13)<<24);    //P0.13 = CTOUT_0

We need to use this pin as GPIO input pin while reading ACK from follower and also for reading CEC data.
We tried deassigning SCT output to that pin and using as GPIO, also used GPIOSetDir( 0, 13, 1 ); to set direction as input. But none of these worked.

So, we need to know if there is any way this can be done.
