I have  a "mystery" problem.

All my registers for the TC port are set properly:

 

MCF_GPIO_PTCPAR=0x00;

MCF_GPIO_DDRTC=0x0F;
 

I have no problems to trigger PTC[1], PTC[2] or PTC[3],

but I can not drive PTC[0], pin does not go high when I set

MCF_GPIO_PORTTC=0x01;

or

MCF_GPIO_SETTC=0x01;

 

I have verified the status of both control registers they are set tot he values I specified for them.

Would could cause this problem?
