[Inverted]

I just had a question about how the joystick buttons are programmed. We're using a joystick that has more buttons than the default code has assigned. I was looking at how they're assigned, and just wanted to know if the "bit#" at the end of the RC feedback variable corresponds to the pin on the connector. In other words, say the button I want to assign uses pin 14 of the connector, would that be "xx.xxxxxx.bit14"? If not, how would I be able to figure out the bit value?
