LAUNCHXL-F28069M

I am using Energia 17 environment with LAUNCHXL-F28069M board. I would like to implement PWM signal on two pins. One signal for example with 30% duty cycle and second inverted to the first one. It means when 1st pin is HIGH the 2nd should be LOW and conversely. In arduino language is only one function for PWM "analogWrite(80,100)". How to set inverted PWM signal in the same phase on second pin?

  I think the command below would work:

  pin_2_state = !digitalRead(pin_1); 

  digitalWrite(pin_2, pin_2_state);

  Keep in mind that this doesn't add dead-time between pin  1 and pin 2 though.
