you are not making sense.
pwm pin low - 0v high = 3.3 v
What I want is, after "reset", the servo motor is supposed to be off, the pin is 3.3V, and when PWM starts, the servo is supposed to be started, the pin is 0V.

you will need an external inverting buffer

Read the datasheet. It will tell you the state of the pin after reset, before the SW has run..

Do a PDF search for the pin number.Gerald

I don't really care the status in short moment. The reason behind my question is:
"I want the pin to be 0V when PWM is working, because I want to reduce the power drain from my BeagleBone board to feed the PWM pin. It is similar to why we have GPIO at 0V to turn on the LED."
It will be good if you can point me where to read in the datasheet. I feel difficulty reading the whole document.
