i want to create a PWM Signal with open drain output at the Pin P1[18] on my LPC1769.

When I configure a normal PWM Signal it works very good, but when I configure the Pin as open drain, nothing changes..
For setting the Open drain function I am using the function from LPCOpen.

Is it possible to create an open drain PWM signal and if, what is my fault?

I want to control a servo, which needs a PWM with 5V. The PWM cable has a 5V Pull up.
