Note on terminology: P:nn is shorthand for port nn, e.g. P:04 refers to port 4.
A note about 83+BE ports: On the 83+BE, many of the ports have been mirrored to the 00h-07h region. If a port is mirrored, when it is being read, take the bitwise-AND with 07h to find the actual port being accessed. Writes to mirror ports are not ignored.
Legitimate 83+BE ports (the rest are mirrored):
- Read values - 00h-07h and 10h-13h are original ports
- Write values - 00h-07h, 10h-13h, 14h, and 16h are original ports
Please note: The TI-84+CSE uses the same ASIC as the TI-84+/SE; it just has a different screen and controller. Therefore, these pages also cover the TI-84+CSE.
