C.1 DIO Interface Introduction

The DIO connector on the KINO-9652 is interfaced to GPIO ports on the IT8712F 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 IT8712F

Super I/O chipset.
