D.1 Introduction
The DIO connector on the PCISA-BT is interfaced to GPIO ports on the Super I/O chipset.
The digital inputs and digital outputs are generally control signals that control the on/off
circuit of external devices or TTL devices. Data can be read or written to the selected
address to enable the DIO functions.
NOTE:
For further information, please refer to the datasheet for the Super I/O
chipset.
The BIOS interrupt call
INT 15H
controls the digital I/O.
INT 15H:
AH – 6FH
Sub-function:
AL – 8
:Set the digital port as INPUT
