There are lots of programming resources for the Atari at www.atariarchives.org.

Specifically, try here: http://www.atariarchives.org/agagd/appendixa.php

JOYSTICK/PADDLE I/O

624-631 ($270-$277) Paddle Game Controller (PADDL0-PADDL7)

A number between zero and 228 ($E4) is returned in these locations for each of the seven paddle potentiometers.

632-635 ($278-$27B) joystick Controller Port (STICK0-4)

These locations return one of nine possible joystick positions for each stick. These values range from 5-15 (35$F). These values are 15 when the joystick is centered or in the neutral position.

636-643 ($27C-$283) Paddle Trigger (PTRIG0-PTRIG7)

Used to determine if the button on each paddle is pressed. A zero is returned if it is pressed and a one is returned when it isn't.

644-647 ($284-$287) joystick Trigger (STRIG0-STRIG3)

These locations are used to indicate whether the joystick button is pressed. A zero is returned if it is pressed, and a one is returned when it isn't.
