E.1 Introduction
The DIO connector on the NANO-QM871-i1 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.
E.2 DIO Connector Pinouts
The following table describes how the DIO connector pins are connected to the Super I/O
GPIO port 1.
