Teensy 3.1 internal pullup enabled pinsl

[zachtos]

Which pins have internal pullups enabled? I know 0-33, but what about the analog only input pins, A10-A14? Do I need to use 10K pullups if using as push button inputs?

You cannot use the analog only pins for push button inputs (i.e. digitalRead). You can only use A10-A13 with analogRead, and you can only use A14 with either analogRead or analogWrite.

I understand that, but you can say if Analogread is LOW, then a button press was detected. Question is is there an internal pull up option on those pins?
