PWM in CE 6.0

Hello,
I'm trying to use the PWM output (TOUT1) available in the Connector 4,
I've modified the PWM driver to do so, but it didn't worked.
I've test the same code ( register values ) in a No-Os aplication and it
works, but when I move inside the driver, it stops working

I've tried to acess the register using two ways, the way domodom does in
it's GPIO driver and using the same data structure that the PWM driver has,
in both, the screen freezes after exiting the program,
using the way like domodomm I've got the TOUT1 pin high, but not PWM...

does anyone have tried this ? anyone know if TOUT1 is used for something
else ?

thanks !

Cristiano

ps: attached I send the PWM source code
