E.1 Introduction
The DIO connector on the TANK-871-Q170i series is interfaced to GPIO ports on the
Super I/O chipset. The DIO has both 4-bit digital inputs and 4-bit digital outputs. 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:
