Is it possible to gate PWM output using another pin?

[Liam]

This is not really a problem - more like an enquiry

Is it possible to gate PWM output using another GPIO pin e.g. if the second pin is low then so its the PWM otherwise the PWM pin is operating normally?

Sorry not sure if I understand your questions. Do you want to switch the output pin of the PWM based on input from another pin? You can't do this purely in hardware, but you can use software interrupts on the input pin which then reconfigures the PWM to use another output pin.
